Features1Function: 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 2The pH will indicate if the solution is acidic or basic, but is not a measure of acidity or alkalinity 3Work in liquids though special probes are sometimes used to measure the pH of semi-solid substances. A pH meter consists of a special measuring probe (a glass electrode) connected to the body which measures and displays the pH reading 4BNC Connector, suitable for most pH meter and controller with BNC connector 5Suitable for wide range of application: aquariums, hydroponics, laboratory etcSpecificationFeatures:1.
