Online conductivity monitor

CR300Online conductivity monitorProduct Introduction

CR300The industrial conductivity (TDS) instrument uses high-performance CPU chips and SMT surface mount technology to measure conductivity/TDS and temperature, perform temperature compensation, and automatically convert range. It has high accuracy and good repeatability. It can continuously measure and control the conductivity (TDS) values of various industrial water,Widely used in industries such as scientific experimental equipment, chemical, pharmaceutical, environmental protection, metallurgy, papermaking, food, beverage, and water supplyBased on the environment and characteristics of the water industry, combined with power supply standards, and considering the electrical design specifications for special environments, 220V AC and safe low-voltage 24V AC and 24V DC power supply options have been added.

CR300Online conductivity monitorProduct Features

·Chinese English interface: Designed in both Chinese and English to eliminate language barriers and meet the needs of customers in various regions.

·One set of high and low normally open relays for alarm: real-time monitoring and measurement of EC conductivity/TDS values, 4-20mA current output, upper and lower limit alarm control.

·Intelligent design, simple and convenient: autonomously select electrode constants based on the liquid to be tested. Set the transmission parameters by yourself. The conductivity temperature compensation coefficient and TDS conversion coefficient can be freely adjusted.

·Wiring port and transmission port, easy to connect: RS485 can be customized, and through RS485, it is easy to connect to a computer and save data.

·The conductivity electrode has a sensitive response.
