TR-308H COD ammonia nitrogen total phosphorus turbidity (four parameters)
The instrument is widely used in emergency monitoring, sewage treatment, chemical, pharmaceutical, hospital wastewater, food, printing and dyeing indu
Product details

Instrument Overview:


The TR-308H COD ammonia nitrogen total phosphorus turbidity analyzer is developed and designed based on authoritative certification methods. It can measure four parameters in water: COD, ammonia nitrogen, total phosphorus, and turbidity. The detection principles of each parameter comply with the recognized methods in the environmental protection industry. Through imported cold light sources and narrowband interference technology, the absorbance of each water sample is detected by spectrophotometry at specific light source wavelengths. After automatic data processing by a microcomputer, the concentration values of COD, ammonia nitrogen, total phosphorus, and turbidity in the sample are directly displayed in units of mg/L or degrees.
