Product overview
Membrane residual nitrogen, total nitrogen and chlorine dihydrogenation electrode are composite digital electrode using membrane amperometric method. Detection part using special permeable membrane technology, with resistant chemicals (mainly surfactant owner) interference, reduce PH dependence, sensor is not limited by water quality conditions, can be applied with tap water, swimming pool, sewage treatment, medical wastewater, industrial wastewater environment, sensor reaction speed, stable performance, low cost and less maintenance, to provide users with reliable and accurate data.
Typical applications, and the main features
Conventional drinking water, tap water, swimming pool water and aquatic products are basically not affected by PH.
Breeding, seawater. Digital signal data internal processing, without electromagnetic interference.
Medical wastewater and medical sewage. Stable work, fast response speed.
Dosing equipment, circulating water and cooling water. No zero-point calibration is required.
Low cost, less maintenance workload.
