Product description

Technical indicators

- typical application

Nitrogen nitrate (NISE) analyzer is suitable for the nitrification and denitrification process of wastewater treatment plants. The discharge of industrial wastewater cannot exceed 30%

-Instrument characteristics

● New generation sensor and membrane head performance is more stable

● Can automatically compensate for the influence of interfering ions

● Built-in matrix calibration

● The sample does not need pretreatment, suitable for 24/7 online monitoring

● The new protective coating ensures a longer service life of the membrane head

● Can be connected with digital SC controller platform

● Optional cleaning device to reduce maintenance

- working principle

The nitrate nitrogen (NISE) analyzer uses ion selective electrodes. The NISE sc sensor consists of a chloride ion selective electrode, a pH electrode (reference electrode) and a temperature electrode to form an integrated electrode. Several parameters in the integrated electrode or sensor cylinder (CARTRICAL technology) can be corrected to reduce interference. The analyzer can perform flexible online correction to further improve the accuracy of the measurement.
