It is suitable for laboratory or on-site online rapid analysis of water, tap water, discharged wastewater, high concentration sewage and various solutions in Rivers and Lakes

COD content.

?The instrument selection valve component will select the timing of reagent samplingFlexible and diverse channels, versatile functions, with small dead ends

Advantages such as size, easy maintenance, and high lifespan.

?The instrument achieves precise measurement of reagents through a visual photoelectric system, overcoming quantitative errors caused by wear of peristaltic pump tubes; Simultaneously achieving the precision of trace reagentsDetermine the dosage, each dose is only1Milliliters, greatly reducedReagent usage.

?Peristaltic pump negative pressure suction, between reagent and pump tubeThere is always an air buffer zone to prevent corrosion of the pump tube; At the same time, it makes the mixing of reagents more concise and flexible.

?High temperature and high pressure digestion system accelerates the reaction processOvercoming the corrosion of equipment caused by the volatilization of corrosive gases in open systems.

?Adopting imported modified polytetrafluoroethylene transparent hosePipe diameter greater than 1.5mmReduced particle blockage in water samplesRate.
