Introduction

A residual chlorine meter is an instrument used to measure the concentration of residual chlorine in water.
Residual chlorine refers to the amount of chlorine remaining in the water after the disinfection process, which ensures that the water remains safe from microbial contamination.

Application

Drinking water, industrial process water disinfection process of hypochlorous acid
(HOCL), residual chlorine concentration on-line monitoring, such as reverse osmosis
membrane treatment process of residual chlorine water monitoring

Water treatment

Sewage treatment

foodstuffs

Advantages

1.LCD display with backlight, English operationinterface.
2.Calibration and setting can set cryptoguard.
3.Technical parameters can be set with buttons on site.
4.High stability ,high accuracy, can measure residual chlorine and temperature.
5.Temperature compensation.
6.Multiple output (2 relays,4- 20mA).
7.Supper anti-interference design can be for strong interference with field operations and anti-electromagnetic interference.
8.The built-in memory chip ensures that the parameters and calibration data are not lost when shut down or off normally.
9.Can automatically detect the temperature probe and enter the automatic temperature compensation program.
