Product Introduction
Circulating water salinity/conductivity sensorDesigned for swimming pools, hot springs, and SPA water treatment, with a range of 0–10 ppt, paired with automatic salt and chlorine generation systems, precisely controlling disinfectant output through salinity feedback. The electrode head adopts a flat self-cleaning design, reducing hair and grease adhesion, extending the maintenance cycle to 6 months.
Industrial-grade online salinity sensor – four-electrode design / anti-polarization / RS485+4-20mA dual output / suitable for seawater and high-salinity wastewater
Used for continuous monitoring and control of conductivity and temperature values of aqueous solutions. Widely used in power plants, petrochemical, metallurgy, paper industry, environmental protection water treatment, light industry electronics and other fields. Such as monitoring and control of raw water and product water quality in water treatment equipment like power plant cooling water, makeup water, saturated water, condensate water and boiler water, ion exchange, reverse osmosis EDL, seawater distillation, etc.
