Code: BSQ-EC-2019
General introduction
EC/ER/pH/ORP-2019 series transmitter mainly used for the water quality monitor sensor signal output, by 4-20mA, RS485 or TTL, the sensor output weak signal is enlarged to transmit, can be convenient for PLC, configuration software and SCM to communicate by adopting standard communication protocol MODBUS protocol.

EC/ER/pH/ORP series transmitter is widely used in metallurgy manufacturing, power, light industry, textile, water treatment equipment, water pipe network and the scientific research and other industrial sectors.

Transmitter series introduction
Note: A module of the transmitter can only be equipped with one sensor, EC/ER is a module, and PH / ORP is a module.

①: EC conductivity transmitter; range: 0 ~ 4000us / cm, 0-10/20/200mS
②: ER resistivity transmitter; range: 0 ~ 18.2MΩ
③: pH transmitter; range: 0 ~ 14.00 pH
④: ORP redox potential transmitter; range: -2000 ~ + 2000mV
