Product introduction

CL-8000 residual chlorine detector is an online intelligent residual chlorine detector produced by our company with foreign technology. It uses imported components and osmotic membrane heads, based on polarographic analysis technology and advanced production process and surface mounting technology. 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/English menu operation, notebook storage of measurement data, 485 communication and other functions.

It is widely used for automatic dosing of circulating water, chlorination control of swimming pools, continuous monitoring and control of residual chlorine content in water solutions in drinking water treatment plants, drinking water distribution networks, swimming pools, hospital wastewater, water quality treatment projects, etc.

main features

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

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

◇ Imported components and residual chlorine film head (polarographic principle) are used.

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

◇ Multi parameter simultaneous display: residual chlorine value, hypochlorite value, PH value, temperature, output current, etc. are displayed simultaneously, 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 PH compensation function and 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.

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

◇ The core devices are all from foreign famous brands.

◇ Power failure protection > 10 years.
