Qiwei AD-83T Benchtop Ammonia Nitrogen Detector

Introduction

The sources of ammonia nitrogen in water are mainly the decomposition products of nitrogen-containing organic matter in domestic (CN) sewage under the action of microorganisms, certain industrial wastewater, such as coking wastewater and wastewater from synthetic ammonia fertilizer plants, and farmland drainage. In addition, in an oxygen-free environment, nitrite present in water can also be reduced to ammonia by microorganisms. In an aerobic environment, ammonia in water can also be converted into nitrite, and even continue to be converted into nitrate. Determination of various forms of nitrogen compounds in water is helpful to evaluate the status of water pollution and "self-purification". When the ammonia nitrogen content is high, it can be toxic to fish.

Principle of Detector  

This instrument uses the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Human error is eliminated, so the measurement resolution is greatly improved.
