Application
ARCL200 used for drinking water treatment plant, drinking water, tap water, swimming pool, cooling circulating water, water treatment engineering, etc.
Main features:
1. The large LCD display.
2. Can restore factory settings.
3. Manual/automatic PH compensation function and temperature compensation function.
4. Communication function (optional) : has the RS - 485 communication interface (MODBUS protocol part compatible).
5. Photoelectric isolation 4-20mA current output.
6. Hysteresis quantity any setting function, avoid switch relay frequent action.
7. Watchdog functions: ensure that instrument won't crash.
