Product Details

Introduction:

The PHS-3C precision grade acidity meter is a 3 1/2 digit LED digital display acidity meter (hereinafter referred to as the instrument). The instrument is suitable for sampling, measuring the acidity (pH value) of the aqueous solution and the measuring electrode potential (mV value) in the laboratory, medicine, factory, school, chemical, environmental protection, and laboratory of the mine. If equipped with an appropriate ion-selective electrode, it can be used as a potentiometric titration analysis terminal indicator.
