pH Tester Designer Water
We have a wide selection of pH tester available for you to choose from. If you scroll down the page we have a comparison guide that you can use to choose the features in the meter that you want. Designer Water is the exclusive agent for HM Digital in Southern Africa.
A Digital 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 or liquid 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.
These digital pen style pH meters are ideal instruments for anywhere you may need to test pH levels. These devices are economical with high precision, digital readout, LCD display screen, waterproof design or waterproof and a high sensitivity. Our devices are very accurate, cost effective, reliable and simple to use.
We have a selection of pH tester so you can choose which unit is suitable for your requirements:
What Is pH?
pH, or Potential of Hydrogen, is a measure of the acidity or alkalinity of a solution. Aqueous solutions at 25°C with a pH less than seven are considered acidic, while those with a pH greater than seven are considered basic (alkaline).
A pH meter can be very useful in a variety of situations, from measuring drinking water to pools water, or for many industrial or commercial applications.
HM Digital’s PH-200 is an extremely reliable pH meter that is very easy to use, easy to calibrate and offers excellent repeatability. Compared to chemicals or paper strips, where questionable color comparisons are required, with the PH-200, it’s a simple matter of turning the meter, dipping it in the liquid and reading the pH value on the LCD display.

What is a Ph Tester Used For?
A pH Meter is an electronic device used for measuring the pH which is either the concentration of Hydrogen ions in an aqueous solution or the activity of the Hydrogen ions in an aqueous solution. The pH will indicate if the solution is acidic or basic, but is not a measure of acidity or alkalinity.
What is PH and how does it measure the concentration of acids and bases?
pH. The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
