Product details
PHS-3B precision pH meter is a device with automatic temperature compensation, capable of measuring 31/A pH meter with a 2-digit LED digital display (hereinafter referred to as the instrument). The instrument has automatic temperature compensation for pH value and manual temperature compensation. Using digital temperature display to reduce visual errors in measurement. The instrument has temperature measurement function. It can display temperature, pH, and mV values. The instrument is suitable for sampling and measuring the temperature, pH, and electrode potential (mV) of aqueous solutions in laboratories such as research institutes, schools, factories, hospitals, and mines. If equipped with appropriate ion selective electrodes, it can be used as a potential titration analysis potential change display.
