Dual-wavelength Water Sensor

The dual-wavelength spectrum sensor, based on the principle of ultraviolet absorption spectroscopy, can measure organic components in water; and has a turbidity compensation function effectively improving the accuracy of actual water sample measurement. It is suitable for the monitoring of domestic sewage, industrial waste water, watershed, etc. Compared with conventional chemical detection, it has the characteristics of high reliability, zero pollution and zero delay, and realizes real-time online monitoring of organic pollutants.

It can be matched with our DL series data collector and WQS-Server cloud service to realize remote real-time monitoring of data, operation and maintenance of equipment.
