Product Description:

The residual chlorine detector is an online intelligent residual chlorine detector imported from foreign technology by our company. Have English menu operation, Notepad storage data, 485 communication interface and other functions. It is widely used for the continuous monitoring and control of the residual chlorine content in the water solution, such as the control of circulating water and the control of the adding chlorine in the swimming pool, the drinking water treatment plant, the drinking water distribution network, the swimming pool, the hospital waste water, the water quality treatment project and so on

Main Features:

• Waterproof, dust proof, moisture-proof (IP65), high-end design look.
• high precision, high stability and preferable antijamming ability.
• Large screen LCD display, support Chinese menu (switching from each other).
• Multi-parameters display simultaneously, such as: residual chlorine , Hypochloric acid value , PH, temperature , current-output, easy to see and read, And there is measurement range exceeding the limit.
• Automatic / manual PH compensation and temperature compensation.
• Communicating function : RS-485 communication function and 4-20mA adopt photoelectric isolation technology. 
• With automatic cleaning function, use running water to cleaning device.
• Automatic identification of PH standard solution and capable for factory reset.
• Watchdog function: make sure the instrument does not crash.
• Power off protection>10 years.
