We analyzed some of the popular products on the market based on quality and performance and found the VANTAKOOL Digital a wise option. Offering wide use, this model is suitable for both laboratory and household water testing applications. It can be used to test the pH balance of drinking water, as well as the water solution in aquariums, pools, Reverse Osmosis water systems, hydroponics systems, spas, and a variety of other purposes. Engineered to deliver results fast, this model guarantees accurate results, even with variability in water temperature. This is thanks to the Automatic Temperature Compensation feature. If the VANTAKOOL Digital is constantly out of stock, you can give the Feramox Digital a try as it makes a good second option.
Being able to find the best water pH meter is not going to be an easy task. 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.
Top water pH meters reviews in 2019
Finding a good-quality pH meter can be tedious. Faced with countless options on the market, the buyer will have to do their own research and evaluation of which would be a suitable product to address their needs. We have featured what we believe are top notch performers in the field.
The VANTAKOOL Digital can be used for both laboratory and household purposes. It is suitable for testing the pH balance of the water in pools, aquariums, spas, Reverse Osmosis (RO) water systems, hydroponics, and in the drinking supply. Versatile enough for a wide variety of applications, this model helps ensure that water quality is of consistent levels regardless of its purpose.
Able to read values and deliver them quickly, this pH meter also offers consistent accuracy. It is equipped with a revolutionary Automatic Temperature Compensation feature.
This component makes it possible for the pH meter to counterbalance automatically any change in temperature when performing readings. This means stability in values.
Another thing to love about this model is how it eliminates the need to use litmus strips and color charts. In the first place, comparing a dipped test strip to a color chart is prone to errors and can often be subjective. Thanks to this pH meter, you have a safe and convenient yet effective way of determining the water quality.
