JIRS electrical conductivity meter transmitter with sensor 4-20mA or RS485 for water quality analyzer EC/TDS-TRA-600
EC/TDS TRA-600 online EC/TDS transmitter is an accurate instrument used for industrial on-line EC/TDS measurement and EC/TDS controlling.
The instrument is easy to install and use, operates safely, has a strong adaptability to the environment, and requires little maintenance. It’s widely used the measurement and control of pure water in the fields of pharmacy, chemical industry, electronic industry, food industry and beverage industry.This instrument features switchable display of conductivity (EC), total dissolved solids (TDS), millisiemens (mS) and temperature values. It can also provide an isolated 4-20mA current signal output or RS485 output, and is equipped with high and low limit relay control output functions.
