NoboModel NS-YD301 -Salinity Digital Sensor

SHARE

The salinity digital sensor is a new generation of intelligent water quality detection digital sensor which researching and developing by our company. It uses a high-performance CPU chip to measure the salinity and convert it into a salinity value.It uses a high-performance CPU chip to measure conductivity and convert it to a salinity value. Can view data, debug, maintenance, etc. through mobile APP or computer. It has the characteristics of simple maintenance, high stability, excellent repeatability and versatility, and can accurately measure the conductivity and salinity value in the solution. It is widely used in the continuous monitoring of conductivity and salinity values in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water.
