Technical Indexes

The sample to be tested does not require any pretreatment. The water sample riser is directly inserted into the system water sample and the total nitrogen concentration can be measured. The maximum measurement range of the equipment is 0~500mg/L TN. This method is mainly used for on-line automatic monitoring of the total nitrogen concentration of waste (sewage) water discharge point source, surface water, etc.3.2 Systems definition
