Performance characteristics


purpose

Product use: Used in drinking water treatment plants, canning plants, drinking water distribution networks, swimming pools, cooling circulating water, water quality treatment projects, and other occasions that require continuous monitoring of residual chlorine content in aqueous solutions.




Product Features

Equipped with automatic temperature compensation.

Output standard Rs485 (Modbus/RTU protocol) digital signal.

Rs485 signal facilitates connection to third-party devices such as PLC, DCS, industrial control computers, general controllers, paperless recording instruments, or touch screens.

Parameter settings are more convenient and efficient.

The calibration function provides a simple and fast calibration method.

Real time data transmission allows you to obtain timely and accurate data on monitored water bodies.

The patented fluoride ion probe has an internal reference solution that slowly seeps out from the microporous salt bridge under a pressure of at least 100KPa (1Bar). This reference system is very stable, and the electrode life is longer than that of ordinary industrial electrodes.
