Laboratory Ammonia Nitrogen Detection Instrument

The laboratory ammonia nitrogen detector adopts the Nessler reagent spectrophotometric method. Ammonia nitrogen in the water sample reacts with the reagent to form a yellow-brown complex, and the ammonia nitrogen concentration is calculated by measuring the absorbance. It is used to determine the ammonia nitrogen content in water bodies and industrial wastewater, thereby monitoring the degree of water pollution.
Selection
When selecting, consider that the measurement range should cover the sample concentration, the detection limit must meet standard requirements, and the operation steps should be simple and fast. The instrument should have calibration functions and data storage capabilities. Choose a manual or automatic model based on the sample volume, and confirm the stable supply of supporting reagents.
