Qiwei PHS-3C desktop precision pH meter Range 0~14pH

Introduction

Qiwei PHS-3C  pH meter (desktop precision type) adopts white backlight, which can display pH value or potential mV value at the same time. It is suitable for sampling and measuring the pH value and potential (mV) value of water u solution in laboratories of universities, research institutes, environmental monitoring, industrial and mining enterprises and other departments.

Product principle

The PHS-3C  pH meter converts the activity of hydrogen ions in the aqueous solution into electrical energy by the sensor (pH composite electrode), and the electrical energy is input to the instrument, which is converted into digital display by A/D after operation and current detection. The above electrical energy conforms to the Nernst equation.

Operating Environment

(1) Relative Humidity: ≤80%;

(2) Ambient temperature: 5~40℃;

(3) Measured solution temperature: 5~60°C;

(4) Power supply: 220V/50Hz power supply;

(5) Do not be disturbed by large vibrations and strong electromagnetic fields.

Parts and Functions
