Product description

Technical indicators

- typical application

In drinking water, surface water, industrial production process water, sewage treatment and other fields, continuous monitoring of the concentration of nitrate dissolved in water is especially suitable for monitoring sewage aeration tanks to control the denitrification process.

-Instrument characteristics

● International general technology, proven and highly accurate ultraviolet light absorption method

● No sample pretreatment, fast reaction analysis, no reagents, no sampling equipment

● There are three different probe configurations to choose from

● The sensor has self-cleaning function

● Two installation methods for immersion and flow cell are available

● Low maintenance and low operating cost

- working principle

NO3- absorbs at 210nm ultraviolet light. When the probe is working, the water sample flows through the slit. When the light emitted by the light source in the probe passes through the slit, part of the light is absorbed by the sample flowing in the slit. To calculate the concentration of nitrate.
