Online total phosphorus meter, TPG-3030


#Online total phosphorus meter, TPG-3030


TPG-3030 online phosphorus meter is developed by BOQU Instrument, BOQU has completely independent intellectual property’s the world-class instrument to measure toal nitrogen.This total nitrogen analyzer is simple to measure, and the sample to be tested does not need any pretreatment. The water sample riser can be directly inserted into the system water sample to measure the total nitrogen concentration. The maximum measuring range of the equipment is 0~500mg/L TP. This method is mainly used for online automatic monitoring of total nitrogen concentration such as waste (sewage) water discharge point source and surface water.

Main features

Unique design makes this product have lower failure rate, lower maintenance, lower reagent consumption and better performance than similar total phosphorus instruments

Select valve assembly: select reagent sampling timing.

Metering component: Accurate metering of reagents through visible photoelectric system, which overcomes the quantitative error caused by wear of peristaltic pump tube; at the same time, it realizes accurate quantification of trace reagents, each dose is only 1.5 ml, which greatly reduces the reagent usage

Injection assembly: peristaltic pump suction under negative pressure, there is always an air buffer between the reagent and the pump tube to avoid corrosion of the pump tube

Sealed digestion component: high temperature and high pressure digestion system, speeding up the reaction process, overcoming the corrosion of corrosive gas volatilization of the open system

Reagent tube: It adopts imported new PTFE transparent hose with a diameter of more than 1.5mm, which reduces the probability of water sample clogging
