With so many brands and models that you have to scrutinize and research about, making a purchasing decision will not be a simple thing. We have outlined in our buying guide the exact points of consideration when making this kind of investment.
It won’t do to simply settle for any product in the many water pH meter reviews. You will need to know how easy the digital device will be to use. The instructions in the user manual will help if they are clear and to the point. However, much depends on how the instrument itself is designed to be easy to use.
A large, easy-to read LCD screen facilitates viewing of the measured values. Ideally, you should be able to read the values regardless of the viewing angle. If the device has a data-hold function, it will make reading and recording easier, especially when you are testing for monitoring purposes.
Since plenty of digital pH meters measure not just the acidity and alkalinity of water, toggling from one parameter to another should be easy to do.
You should be able to obtain a reading in minutes, with some high-quality models providing one in just seconds.
A lightweight device will be easy to operate with one hand. Compare that to using conventional test strips and a color chart, and you would quickly shift to digital models too. You should be able to operate the device with just one hand. Just immerse the probe or electrode into the solution or water then wait for the reading to stabilize. It’s that simple!
A backlit LCD screen allows you to do testing even when lighting conditions are not ideal. For easy portability and storage, a carrying case offers convenience.
Reliability of results
A good pH meter ensures repeatable, consistent accuracy. If you can, find a model that has a slim margin of error or accuracy range, such as ±0.01 to ±0.02. This will ensure reduced erroneous values, which is critical especially when the solution is really pH sensitive.
Oftentimes, any slight variances in pH affect the quality of the liquid being tested. It could influence the taste, usability for making mixtures, and even safety for drinking. That is why the margin of error should be very narrow.
You will want a wide measuring range despite a limited accuracy range. This aspect will enable you to ensure that readings are not limited to a low value. It will also ensure greater measuring potential for various liquids.
Check out units offering Automatic Temperature Compensation. This detail ensures the tool can read values effectively even when the temperature of the test liquid is not constant or standard. The feature enables the tool to compensate for any temperature change and proceed to deliver a precise reading. This point ensures stability.
You might even find devices that remind you when it’s due for re-calibration. This is vital since you wouldn’t want to be getting errors in values.
The tool should also operate on batteries for extended periods, giving you countless hours of use.
Versatility and functionality
Any pH meter for sale should be ready to do its job right out of the package. While many models need to be calibrated at the onset, the process is usually easy. After that, it’s ready to go before the next re-calibration. A lot of ph meters measure not only the acidity and alkalinity of liquids but also their temperature, electrical conductivity (EC), and even total dispersed solids (TDS), which is essential for testing purity or concentration.
You should be able to switch from one mode to another with push-button simplicity. Some units are equipped with an auto calibration feature with buffer recognition. Calibration solutions simplify the initialization process.
You would want the device to enable you to use it for a variety of applications.
A bit more about precision
If you are not familiar with using a pH tester, then you should know that these meters are available in three main types of construction, namely the benchtop one, the portable handheld models, and the pen-style units. With this being said, the benchtop products are usually the most precise, but they are also more expensive and less mobile, so they are not suitable for anyone.
However, it’s true that precision is exactly what you need from such a pH tester, whether you are working in a lab or not. The great part about pen-style and handheld models is that anyone can use them, thus improving many processes in our lives, even if we’re talking about someone who simply wants to obtain better results when it comes to gardening.
Specialists who are working in a lab or professional conditions and want to obtain extremely accurate results for a specific purpose, such as brewing, need to look for a unit that comes with at least +/- 0.01 pH units. However, for general needs, meters that offer a +/- 0.1 pH unit variation can work very well as well. It all depends on what you are trying to achieve.
Calibrating the unit is also very important since you want to make sure that you get the most accurate results possible every time you are using it. This principle applies whether you are working in a lab or not, so once you get such a device, you need to make sure that you know how often it needs to be calibrated and, more importantly, how to properly do this.
When it comes to calibration, there are two different ways in which this can be done, namely either automatic or manual. The process depends on the type of device you have as well, so make sure that you carefully read the instructions provided within the package or issued by the manufacturer.
The manual calibration means that you will need to adjust two knobs after the probe is placed in the right calibration buffer. However, if you have a device that includes automatic calibration, then the process is much easier. If you are planning to use one of these meters for soil pH measurements, it’s a good idea to see if there is any particular method in order to do the calibration in the right way.
In case you are noticing any issues when it comes to this process, you can always look for more information online on these meters and see if there’s something that you should be doing differently. If you cannot seem to figure it out, asking the manufacturer for details is the way to go. This way, you’ll know whether you have a unit that doesn’t work properly, and thus you can get a refund or a new one.
However, if you go for a high-quality product, this should not be an issue. Next, you also want to see what you are supposed to do in order to maintain it throughout time, as this process definitely helps you get more use out of it. For instance, if you are using your tester for soil, you will need to clean it after each use and make sure that everything is in order before storing it.
How often should a pH meter be calibrated?
Going through the calibration process is what makes pH meters reliable, so this is not a step that you want to skip. With this being said, the answer to the question above depends on a few factors that you should bear in mind as you are getting ready to use your device.
To begin with, pH testers should be calibrated before each use, and this is especially important when it comes to highly accurate ones used in particular settings, such as a lab. For general use, if you are planning to test the soil for your garden, you can do this process every week.
The answer here can also depend on how often you are using the meters, given that this can greatly influence both their lifespan and their accuracy.
Just like any other product, pH meters do need to be replaced after a while. Therefore, if you are planning to use yours on a daily basis, which is something that can have an impact on their components, such as the electrode, then you need to pay attention to how you calibrate them and ensure their overall maintenance.
There are some particular cases when calibration is definitely necessary, such as those times when an electrode has not been used for a long time. If you’ve stored your device for a while, then you definitely want to make sure that it still works the way it should. The same principle applies if the unit is new and you are using it for the first time.
Along the same lines, you want to calibrate your pH tester if you’ve measured a strongly acidic solution or a strong base with its help. While this may not be the case if you are using it for soil, it’s surely a good idea to make sure that the electrode is working properly after stronger testing.
Moreover, if there’s a big temperature difference between the item you are testing and the buffer, you should do the calibration process once you are done or before using the tester again, as this can influence its accuracy for future readings.
Depending on whether you work in a lab or not, getting accurate readings can be quite important, so you want to make sure that varying temperatures won’t affect the results. Most pH meters include temperature compensation, which is always a useful feature.
However, you want to make sure that you also know the sample’s temperature as well, no matter if we’re talking about soil or something else. This way, you will be able to get even more accurate readings, given that you will be able to properly calibrate the meter.
While some may say that temperature compensation is an overrated feature, the truth is that it can be quite helpful in many situations, especially if you are still rather new to using this type of meter. Moreover, no matter if you are simply testing soil samples for your garden or you work in a professional lab, getting results that you can rely on is the main goal to make your efforts worthwhile.

Frequently Asked Questions
Q: What is a pH meter for water and how do I use it?
A typical pH meter includes two main components, namely the meter itself and the digital element. The first one usually features a simple construction, given that it’s a moving-coil meter, while the digital part includes a display that shows the results. Given that pH meters use electricity principles to test your sample, you have to create an electrical circuit.
This is done by creating an electrical flow using the test solution, and you can easily do this by putting each electrode in it. If the pH meter you choose has two probes, then each one features a different electrode, while more compact units come with two electrodes built inside.
In terms of usage, a pH meter is very easy to handle, and all you need is the sample and the device. No matter the model you choose, you should always read the instructions and make sure the unit is properly calibrated, even if you are simply using it to test some soil.
Q: How is pH measured?
A sample’s pH is measured using some simple principles of electricity. The device needs to measure the hydrogen ions concentration in the probe in order to identify its pH. The idea behind this process is quite simple. If you are measuring an acidic solution, then there are more hydrogen ions that are positively charged than in the case of an alkaline one.
This means that the solution or sample has more chances of producing an electrical current, given certain circumstances. Those of you who are familiar with the way batteries work can think of this as producing greater voltage.
A pH tester acts pretty much like a voltmeter, by measuring the electrical potential (or voltage) of a solution using the electrode and then comparing it with that of an already known one. Then, it uses the difference between the two to figure out what the difference in pH is. That’s why properly calibrating the device is a very important process.
Q: What is the pH of pure water?
The pH value is actually a very good indicator of whether you should drink water from a certain source or not, given that it says if it’s soft or hard. When it comes to the pH of pure water, this is 7, so you can keep this in mind as a reference point.
Water with a pH lower than 7 means that it’s acidic, while water with a pH that goes over 7 means that it’s basic. Water that comes from surface sources has a normal pH range that goes between 6.5 and 8.5, while that extracted from underground systems has a pH range that goes from 6 to 8.5.
If you are not sure whether you should measure the pH of the water you are drinking, it’s good to bear in mind that this can help you determine its corrosiveness, which can ultimately become an issue.
