A pH meter is typically used in gardening, aquarium water testing and pool maintenance. Wine making and cheese making workers also use pH meters to ensure consistent flavor in their products. Another less common use of a pH meter is for stain removal, such as when determining what type of cleaning solution is to be used to clean off stains from carpet or fabric. What sets apart the top rated products in the best soil pH meter reviews?

A.1 Best PH meter

A form factor you are comfortable with

If you want the greatest versatility, a benchtop model provides the best solution. Depending on the model you choose, a benchtop unit accommodates the addition of data loggers, built-in printers and various accessories and probe arms. Most benchtop pH meters are filled with features and offer fantastic precision. They can also feature either standard or extended range.

Standard range pH meters measure the standard pH scale from 0 to 14, enabling use for most applications that involve water-based solutions. Some models have smaller scale, such as from 4 to 10, although these types are not suitable for most lab environments.

On the other hand, extended range benchtop models are perfect for applications that need a base acid beyond the standard pH scale from 0 to 14. The reading may be as high as +20 or a negative one such as -2. Substances such fluorosulfonic acid and triflic acid fall under that category and thus are called superacids. Superacids are typically utilized in the production and maintenance of, organic cations, which act as intermediate molecules to facilitate a variety of reaction, including those that involve the production and research of high-octane gasoline and plastics.

Extended range pH meters come with varying resolutions. For highly sensitive lab applications, a pH resolution of 0.001 is ideal where a reading of three decimal places is needed. Basic lab applications can be handled with a ph resolution of 0.01 to deliver pH readings of two decimal places when needed. For basic lab applications that need a ph reading of one decimal place, you will want benchtop model with pH resolution of 0.1.
Portable handheld pH meters used to be deficient in sophisticated features compared to their benchtop cousins. With advances in technology, many of today’s portable units are designed to be almost as advanced as benchtop models, making them a suitable option for lab and field applications. Some portable pH meters carry a pen-style design for easy carrying in the pocket.

Like benchtop models, portable units also come with either standard or extended range. Measuring the standard pH scale between 0 and 14, standard portable pH meters handle most applications that use water-based solutions. Smaller scale pH meters that read from 4 to 10 are not really designed for lab use. Extended range portable pH meters are used for applications that need a base acid falling beyond the standard scale between 0 to 14, with the reading either as high as +20 to a negative 2 (-2). Triflic acid and fluorosulfonic acid along with other superacids fall in this category and are useful in the production and maintenance of organic cations that are needed in facilitating various reactions including those involving high-octane gasoline research and production along with plastics creation. Extended range portable pH meters come with the same pH resolutions as those of benchtop models.

 

Reliable precision and calibration

A pH meter that has at least +/- 0.01 to 0.02 pH units is needed for brewing applications. This type of pH meter enables testing of mash pH and also offers good detection capabilities for pH rises in beer, which is a sign of autolysis. +/- 0.1 may be too little but for those on a particularly tight budget, such a level of precision may be enough if your only purpose is to obtain the correct mash pH range.

Calibration may either be manual or automatic. Two knobs have to be adjusted with manual calibration, with one knob for the slope (pH 4.00 or 10.00) and the other for the offset (pH 7.00) after the probe is put into the appropriate calibration buffer. With automatic calibration, the instrument can either recognize the buffer on its own or tell you what buffer to put the probe into.

 

A.2 Best PH meter

 

Dependable Temperature correction and other features

A pH meter can come with manual or automatic temperature correction or none at all. The pH of the solution is not the only element that affects the pH probe; it is also influenced by the temperature of the solution, which needs to be known. That being said, with temperature, the actual pH of the solution may also change. Your option here is to always measure pH at a constant temperature or to state the temperature the pH was measured at. Calibration buffers also act in the same concept, with their nominal pH at 25 degrees Celsius for calibrating the pH meter. Aside from that, you may have to know the pH of the solution at its actual temperature. A lot of buffer solutions come with a table that lets you see these pH changes.

An mV readout proves to be necessary because the slope of the pH meter is used to gauge its age. BNC connections are standard for the connection of pH probes. They enable you to enjoy a wider choice of replacement probes since you are not limited to a particular connector design.
