Salinity water quality online tester
Model：ERUN-SZ1S-A-N6
Parameter: Salinity (electrode method)
Salinity meter is an online intelligent salinity meter independently developed by our company. It adopts high-performance CPU chip and SMT patch technology to complete the measurement of salinity and temperature, temperature compensation, high precision and good repeatability. It is widely used in continuous monitoring of salinity value in solution of thermal power, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemistry, food and tap water.
