● 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.
