　　2. Introduction to online residual chlorine meter products

　　The residual chlorine detector is an online 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 polarographic analysis technology, production process, and surface mount technology. Using this series of analytical techniques to 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, swimming pools, cooling circulating water, water quality treatment projects, etc.

　　Key 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.

　　◇ Power failure protection>10 years.
