Introduction

Principle & Structure

Conductivity sensors are glass platinum electrodes. The measuring principle of the instrument is to put two discs (conductive discs) in the sample solution, and add a voltage to the two discs to measure the current. Generally, the voltage is in the form of a sine wave. Conductivity is determined from voltage and current values ​​by Ohm's formula.

Features

● Has good repeatability and stability

● Simple cleaning and activation, and fast balancing;

● Automatic temperature compensation function

● Digital sensor, strong anti-interference ability, long transmission distance;

● Standard digital signal output, special transmitter-free industrial and mining can realize integration and networking with other equipment;

● The on-site installation of the sensor is convenient and fast, realizing plug and play;

● A visual alarm system is set up to provide important alarm functions;

● English and Chinese display can be switched, and it is more convenient to use Chinese.

application
