NH3N type ammonia nitrogen water quality online analyzer (Nessler's reagent method)

Ammonia nitrogen online analyzer

Instrument Overview:

The NH3N ammonia nitrogen water quality online analyzer is designed specifically for monitoring pollution water quality emissions. According to different principles of water sample pretreatment, it is divided into two types of instruments: A and B.

The analysis method of the instrument adopts the Nessler's reagent spectrophotometric method, which complies with the national standard "Determination of Ammonia Nitrogen in Water Quality - Nessler's reagent spectrophotometric method" (HJ535-2009) and belongs to the national Class A method for ammonia nitrogen monitoring, ensuring the accuracy and effectiveness of monitoring data.

The A-type ammonia nitrogen online automatic monitoring device is based on direct colorimetric method and is suitable for conditions with low turbidity or other interference (about 70%)

The B-type ammonia nitrogen online monitoring instrument is based on the exclusion colorimetric method and the national standard "Determination of Ammonia Nitrogen in Water Quality - Salicylic Acid spectrophotometric method" (HJ536-2009)

This instrument is suitable for complex working conditions with significant interference from turbidity and color. It is suitable for over 90% of various complex working conditions.
