Product introduction

The residual chlorine instrument CL-7600 of our company is a microcomputer based online monitoring and control instrument for residual chlorine in water. It uses advanced non membrane constant voltage sensor, without replacing the membrane and reagent, with high sensitivity, rapid signal response, accurate measurement, stable performance and simple maintenance. The residual chlorine measurement and control system in water has the characteristics of convenient use, high accuracy and economy. This series of advanced analysis technologies are used to ensure the stability, reliability and accuracy of the instrument in long-term operation. It has Chinese and English menu operation, 485 communication and other functions.

It is used for continuous monitoring and control of residual chlorine content in water solution in drinking water treatment plants, tank plants, drinking water distribution networks, swimming pools, cooling circulating water, water quality treatment projects, etc.

Main features

◇ The advanced non membrane constant voltage sensor is adopted, which does not need to replace the membrane and reagent, has high sensitivity, rapid signal response, accurate measurement, stable performance, stable zero position, simple maintenance, and is more suitable for low range occasions.

◇ Brand new waterproof, dust-proof and moisture-proof high-quality shell (IP65) technology, surface painting technology, generous and high-end appearance of the instrument.

◇ Large screen dot matrix LCD display, support Chinese and English menus (mutual switching), multi parameter simultaneous display.

◇ The product has high precision, high stability and strong anti-interference ability.

◇ Multi parameter simultaneous display: residual chlorine value, temperature, output current, etc. are displayed at the same time, which is intuitive and easy to read, and there is a prompt for measuring range overrun.

◇ It has the function of restoring factory settings.

◇ Manual/automatic temperature compensation function.

◇ Communication function: interface photoelectric isolation technology, with RS-485 communication interface (partially compatible with MODBUS protocol) (optional), which can convert RS-232. The residual chlorine value corresponding to 4~20 mA current output can be set arbitrarily. Support the company's internal Internet of Things and customized Internet of Things.

◇ Photoelectric isolation 4~20mA current output.

◇ The hysteresis value can be set arbitrarily to avoid frequent action of the switch relay. It has the function of setting the switch value to close and close.

◇ Watchdog function: ensure that the instrument will not crash.

◇ The core devices are all from foreign famous brands.

◇ Power failure protection > 10 years.

◇ ABS plastic shell IP65, waterproof, dustproof and moisture-proof design.
