Acid Meter Technical Description

I. Overview

PHS-3C digital pH meter is an instrument for measuring the pH of a solution. It can also measure the setting and measurement of each parameter value of the electrode potential (mv). It can be switched with a selection switch and has a high-brightness LED digital tube display. The instrument uses composite glass. Electrode, set temperature value also have digital display, and achieve temperature compensation. The instrument abandons the traditional power transformer, using a new type of instrumentation dedicated small switching power supply, so that the instrument has over-current detection throughout the work process, over-voltage, overheating automatically A series of perfect protection functions, such as closing, not only increase the reliability of the instrument, but also significantly reduce the volume and weight. It also enables the long-term reliable and stable operation of the power supply voltage from a wide range of 80V-265V.
