Residual chlorine analyzer

Residual chlorine determinationceremonyIt is an online intelligent residual chlorine detector that uses imported components and permeable membrane heads, based on the new technologyThe polarographic analysis technology and advanced production process and surface mounting technology. By utilizing this series of advanced analytical techniques, we ensure the stability, reliability, and accuracy of the instrument's long-term operation. It has functions such as Chinese menu operation and 485 communication. Used for continuous monitoring and control of residual chlorine content in water solutions in drinking water treatment plants, drinking water distribution networks, swimming pools, cooling circulating water, water quality treatment projects, etc.

​Residual chlorine determinationceremony

Key Features:

◇Large screen dot matrix LCD display, Chinese menu operation.

◇Simultaneous display of multiple parameters: residual chlorineValue, hypochlorous acid value, pH value, temperature, output current, etc. are displayed simultaneously, which is intuitive and easy to read, and there is a range exceeding prompt.

◇ It has the function of restoring factory settings and slope correction.

◇ Manual/Automatic pH compensation function and temperature compensation function.

◇Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol),The residual chlorine value corresponding to the 4-20 mA current output can be set arbitrarily.

◇Optoelectronic isolation 4-20mA current output.

◇ The function of setting the hysteresis value arbitrarily avoids frequent actions of the switch relay, and has the function of setting the switch value to turn off and off.

◇Watchdog function: Ensure that the instrument panel does not crash.

◇The core components are all from abroad.

◇Power failure protection>10 years.
