Ammonia nitrogen analyzer

Ammonia nitrogen analyzer

  • Product Number:LD-TNH
  • Product Difference:Mainly detects ammonia nitrogen content in water bodies, with a 10.1-inch LCD touch screen display

Product Introduction

The ammonia nitrogen analyzer primarily measures the ammonia nitrogen content in water bodies. The device is equipped with multiple light sources corresponding to different detection wavelengths, enabling simultaneous compliance with both the Nessler reagent method and the salicylic acid method for measuring ammonia nitrogen content in water bodies. The Nessler reagent method complies with the environmental standard HJ 535-2009 “Water Quality - Determination of Ammonia Nitrogen - Nessler Reagent Spectrophotometric Method,” while the salicylic acid method complies with the environmental standard HJ 536-2009 “Water Quality - Determination of Ammonia Nitrogen - Salicylic Acid Spectrophotometric Method.” This instrument features intelligent data analysis functionality, displaying data in charts and lists for clear analysis; it has a high-resolution color LCD touchscreen, an Android smart operating system, a Chinese display interface, and a Chinese/English keyboard, offering user-friendly operation for simpler use.

The ammonia nitrogen analyzer can be widely applied in various industries (industrial wastewater, municipal sewage, domestic sewage, and surface water in river basins) for wastewater testing, catering to the diverse needs of different users. It is suitable for monitoring industrial wastewater from sectors such as chemicals, petroleum, coking, papermaking, metallurgy, brewing, and pharmaceuticals, as well as various types of domestic sewage.
