Overview
CL650 online residual chlorine detector
Product Details
Product Name: Industrial Online Residual Chlorine Detector CL650
1、 Product Introduction
The online residual chlorine detector is an intelligent residual chlorine detector produced by our company through the introduction of foreign technology. It uses imported components and permeable membrane heads, and is based on the latest polarographic analysis technology, advanced production processes, and surface mount 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.
2、 Product configuration
（1） Standard configuration
◇ One online residual chlorine instrument
◇ One residual chlorine electrode (5 meters), one spare membrane head, and one bottle of spare electrolyte
◇ One circulation channel
◇ One pH electrode (including one bag of buffer solution at 4.00 and 6.86PH)
◇ Tighten two locking strips
◇ One user manual
（2） , Optional
◇ Installation bracket (1 meter long)
◇ 485 communication interface and 485 to 232 or 485 to USB connector
3、 Main features:
◇ Large screen dot matrix LCD display, Chinese menu operation.
Simultaneous display of multiple parameters: residual chlorine value, hypochlorous acid value, pH value, temperature, output current, etc. are displayed simultaneously, which is intuitive and easy to read, and there is a prompt for exceeding the range.
◇ 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 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 well-known foreign brands.
◇ Power failure protection>10 years.
