Brief introduction

RB-401BPortable TypeCODThe ammonia nitrogen total phosphorus total nitrogen analyzer is designed and manufactured by our company to meet the field application needs of users. The instrument is equipped with a large capacity rechargeable battery.RB-401BPortable TypeCODThe ammonia nitrogen total phosphorus total nitrogen analyzer is used for measuringCODThe integrated machine for measuring ammonia nitrogen, total phosphorus, and total nitrogen parameters is accurate, fast, easy to operate, and directly displays the measured samplesCODAmmonia nitrogen, total phosphorus, and total nitrogen values.

Scope of application:The instrument is suitable for environmental monitoring, sewage treatment, scientific research institutions, and colleges and universities. Suitable for groundwater, surface water, domestic sewage, industrial wastewater, and other types of waterCODDetermination of four parameters: ammonia nitrogen, total phosphorus, and total nitrogen.

2、 Detection principle

RB-401BPortable TypeCODAmmonia nitrogen, total phosphorus, and total nitrogenanalyzerinstrument，CODThe determination adopts the closed catalytic digestion colorimetric method with a digestion tube, the ammonia nitrogen determination adopts the Nessler's reagent colorimetric method, the total phosphorus determination adopts the closed digestion colorimetric method, and the total nitrogen determination adopts the closed digestion ultraviolet photometric absorption method, all of which are from the United StatesEPAAfter recognizing the method, the sample is directly displayed using imported cold light sources, narrowband interference technology, and microcomputer automatic data processingCODAmmonia nitrogen and total phosphorus values.
