Introduction

Principle & Structure

The electrical conductivity represents the electrical conductivity of the material, the greater the electrical conductivity, the greater the electrical conductivity, and vice versa.

The conductivity sensor is suitable for use in almost all occasions, and its robust construction makes it durable for many test sites with harsh conditions.

Features

● The modular design of the board makes the assembly and configuration more convenient.

● Adopt 2.4-inch 128×64 dot matrix screen

● Adopt isolated transmission output, less interference

● It can measure conductance value/TDS, temperature measurement, upper and lower limit control, transmission output, RS485 communication

● High and low alarm functions and hysteresis can be set

● Buzzer, LCD backlight switch function can be set

application

Widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water and other solutions in the continuous monitoring of conductivity value and temperature.
