Model PHS-4A Digital pH Meter------serial products of acidity meter Model PHS-4A Digital pH Meter is a great tool for any laboratory operator and field user, which is one of the most accurate digital pH/mV/Temp meters available in the market.It has the function of ATC (automatic temperature compensation) and MTC (manual temperature compensation), and is suitable to measure the pH or temperature value of solutions and the potential (mV) of electrodes. Furthermore, if it is equipped with an appropriate ion selective electrode, it also can be used to measure the ion concentration or as a terminus display device for potential titration analysis. Its high accuracy and resolution make it suitable even for all the most-demanding solution pH/mV measurement, such as chemical solutions, milk, beverages, juices, water or any other water based liquid.
