EC/ER/pH/series transmitter is mainly used for water quality monitoring sensor signal transmission, through 4-20mA, RS485 or TTL level to amplify the weak signal output from the sensor for transmission, which can be easily communicated with PLC, configuration software, microcontroller, etc. Communication protocol using standard MODBUS RTU protocol.
This product can be widely used in metallurgical manufacturing, electric power, light industry, textile, water treatment equipment, water pipe network and scientific research and other industrial sectors.
Note: EC/ER transmitter module is a general-purpose module and PH module is a general-purpose module. The two modules have the same appearance, different hardware, distinguished by the logo on the panel, so pay attention when using them. One transmitter module can only be adapted to one electrode input.
EC conductivity transmitter range: 0~2000us/cm; optional 0-4000uS, 0-10.00mS, 0-20.00mS, 0-200.0mS;
ER resistivity transmitter; range: 0~18.2MΩ
pH transmitter; range: 0~14.00 pH
Note: One module of transmitter can only match one electrode, EC is a separate module, PH is another module
