Online Intelligent UV254COD Sensor BH-DC18

This instrument uses 254nm deep ultraviolet LED, which is small in size and long in life. The 254nm deep ultraviolet beam is absorbed by the organic matter dissolved in the water during the transmission process, and the degree of absorption is proportional to the concentration of organic matter, so that the content of organic pollutants in the sample can be evaluated by measuring the absorbance of the deep ultraviolet beam. The built-in 365nm wavelength light source is used for turbidity compensation, effectively eliminating turbidity interference.

Features

• Optical measurement, no reagents, no pollution.
• Built-in 254nm and 365nm dual optical paths, automatically compensate for turbidity interference.
• Comes with wiper, with automatic cleaning function to prevent biological attachment.
• Imported LED light source, with small drift, fast response, and more accurate measurement.
• The size is small, the installation is more convenient, and the water quality can be monitored on-line
  without interruption.
• Digital sensor, RS-485 interface, Modbus/RTU protocol.
