Online Conductivity (TDS) Controller ECM-1800

ECM-1800 industrial online Conductivity (TDS) meter can continuously measure and control conductivity value of industrial water. It is widely used for the science laboratory equipment, chemical, pharmaceutical, environmental protection, metallurgy, paper making, food, beverage, water supply industry, etc.
In accordance with the environment and characteristics of water industry, as well as the international power supply standard, considering the electricity design in special environment, the pH meter could be supplied with power 220V AC(EC-1800A), and safe low voltage 24V AC,24V DC(EC-1800B) for selection.

Main Characteristics:
² Chinese and English language display
² Measure Conductivity (TDS) and Temperature, high/low limit control, current output, digital communication
² It can be adjusted the conductivity temperature compensation coefficient and TDS conversion coefficient.
² Two way relay, can control the electrical conductivity (TDS) and temperature respectively, the hysteresis can be adjusted freely.
² Instrument mode isolated transmitting port, can be configured into the conductivity (TDS) or temperature, maximum 300Ω loop resistance.
² Sound alarm function could be set;
² Back light of LCD could select power saving mode, timing automatic off
² High performance CPU, good electromagnetic compatibility
² Have a key to restore the factory parameter function
² Password management avoid non-professional person operation
² It could be set automatic or manual temperature compensation
² pH high limit alarm, low limit alarm, double relay, alarm delay could be adjust
² Instrument mode isolated transmitting port, max circle resistance bigger than 300Ω
² Sound alarm function could be set;
² Back light of LCD could select power saving mode, timing automatic off
² High performance CPU, good electromagnetic compatibility
² Password management avoid non-professional person faulty operation
