5 Best pH Meters (Must Read Reviews) for 2020

A pH meter is a small device that you can use at home or other settings to check the acid/base levels of water, other fluids, and even food.
This tool has a probe on one of its ends, which you insert into the substance being tested. An accurate pH reading is then obtained and displayed on a digital screen.
The pH scale ranges from 0 - 14, where 0 - 6 indicates acidity, 7 - 14 indicates alkalinity, and 7 is neutral.

With a wide array of handy applications, the best pH testers even double as electric conductivity gauges and digital thermometers.
And, more importantly, a pH meter lets you determine the acidity or alkalinity in water in a few seconds. That means you can swiftly adjust the chemicals or get expedited professional service if you think it needs particular treatment.
To top off it all, these pH devices are user-friendly and easy to use for the typical homeowners.

Using a pH meter is also just very objective compared to reading a color pH testing strip. These strips tend to vary by color and brand, so getting a reading depends on how you think the colors look.

• A pH meter just gives you a simple number that’s easy to understand and the same across the board.


• A pH meter also has the advantage of being reusable. You don’t have to throw it away after a single use like most pH measuring tools.


• You can measure with a single meter as many times as you like, saving you money and convenience.

​HM Digital pH/TDS/EC/Temp meter

​The COM-300 is an advanced waterproof combo meter with superior accuracy. The meter measures four parameters: pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS) and temperature. Features include 2 different conductivity conversion factors to convert EC to TDS using the 0.5 (NaCl) or 0.7 (442TM), as well as selectable modes for measurements in the µS, mS and ppm scales. The meter incorporates automatic temperature compensation (ATC) to accommodate for discrepancies in temperature that would naturally occur, and also features digital calibration for easy and precise calibration that will yield better results.

• Very economical conductivity and TDS pocket meter


• Ergonomically designed display to view measurements easily


• Waterproof and dustproof housing


• Stainless steel electrodes


• Built-in belt/pocket clip
