REDOX CONTROLLER CR-421
CR-421 is a simple and accurate stationary device used for continuous redox and temperature measurements in clean water or sewage.
Depending on working conditions, the appropriate type of redox electrode may be chosen and built-in the flow through or immersible head.
The controller is available in three versions:
1. Equipped with two relays to control valves and signalisation system.
2. Equipped with 0 ÷ 20 mA or 4 ÷ 20 mA current loop.
3. Equipped with RS-232 output with a software to collect the data on a PC. Optionally, the connection may be made by USB with use of RS-232 / USB converter (additional equipment).
