Measurement Principle

NO₃ absorbs ultraviolet light at 210nm. During probe operation, the water sample flows through a slit. Light emitted by the probe's light source passes through the slit, where part of it is absorbed by the flowing sample, while the rest transmits through the sample and reaches the detector on the other side of the probe, calculating the nitrate concentration value.

Features

lProbe directly measures via immersion, no sampling or pretreatment required;

lNo chemical reagents needed, no secondary pollution;

lShort response time, enabling continuous measurement;

lSensor has automatic cleaning function, reducing maintenance;

lSimple to use, reliable results, interface operation instructions minimize operational errors;

lEquipped with a visual alarm system providing important warning functions;

lController can be wall-mounted/panel-mounted/clamp-mounted.

Typical Applications

lContinuous monitoring of dissolved nitrate concentration in drinking water/surface water/industrial production process water/wastewater treatment, especially suitable for monitoring wastewater aeration tanks and controlling denitrification processes.
