Applications
Used for continuous monitoring and control of fluoride ion content in aqueous solutions in drinking water treatment plants, power plants, sewage treatment, and water quality treatment projects.
Main Features
◇ Advanced fluoride ion selective electrode method (ISE method), high sensitivity, fast signal response, accurate measurement, stable performance, and simple maintenance.
◇ Large screen dot-matrix LCD display with Chinese menu operation.
◇ Multi-parameter simultaneous display: fluoride ion value, temperature, output current, etc., displayed simultaneously, intuitive and easy to read, with range over-limit prompt.
◇ Factory reset function.
◇ Manual/automatic temperature compensation function.
◇ Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol), 4–20 mA current output corresponding to fluoride ion can be arbitrarily set.
◇ Optically isolated 4–20mA current output.
◇ Hysteresis setting function to avoid frequent switching of relays; includes switch-off and switch-on function.
◇ Watchdog function: Ensures the instrument does not freeze.
◇ Power-off protection >10 years
