pH Meters & Testers

pH meters measure the acidity or alkalinity of a solution. Frequently used in agriculture, food processing, laboratories and aquariums, pH meters test the quality of water, soil, food and other substances.

ETI offers a range of pH meters for different budgets and applications, ranging from easy-to-use pocket pH meters to digital pH and temperature meters with interchangeable electrodes.

All of our pH meters can be recalibrated at the touch of a button when used in conjunction with pH buffer solutions.
