JJF 1424-2013 《Program of Pattern Evaluation of Ammonia-Nitrogen Automatic Analyzers》 Related products

JJF 1424-2013 "Ammonia Nitrogen Automatic Monitor Type Evaluation Outline" is applicable to ammonia nitrogen automatic monitor based on electrode method and photometry method. This outline refers to JJG 631-2013 "Ammonia Nitrogen Automatic Monitor" and GB/T 11606-2007 "Analytical Instrument Environmental Test Method" and other relevant standards. The ammonia nitrogen automatic monitor is capable of continuous automatic monitoring of ammonia nitrogen concentration in groundwater, surface water, domestic sewage and industrial wastewater. Measuring methods include photometry (such as salicylic acid photometry, Nessler reagent photometry, etc.) and electrode method (such as Gas sensing electrode method, ammonia Ion selective electrode method), using these methods can accurately measure the ammonia nitrogen content in water samples. The instrument consists of sampling, water sample processing, detection, data collection processing, display and transmission units, which can achieve efficient water quality monitoring and data management.
