What is PH tester ?

PH tester is an electronic device used for measuring the PH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (A glass electrode) connected to an electronic meter that measures and displays the pH reading, and this tester also can test temperature.

Applications :?

PH meter is an easy tool for testing the level of water quality, popular in water deal industry, household, travelling, and etc, especially hydroponics, greenhouse, horticulture and gardening.
