8-in-1 Water Quality Sensor - PH/EC/TDS/Temp/ORP/Salinity/Specific Gravity Tester with RS485 Output


Product Overview
CWT-MS8-S RS485 8-in-1 water quality sensor features a high-sensitivity, high-temperature/pressure-resistant pH glass electrode that’s adaptable and easy to maintain. As an 8-in-1 device, it measures pH, ORP, temperature, TDS, conductivity, specific gravity, and salinity (ppt/%).
Powered by a 32-bit MCU and RTOS system, it ensures precise readings. With ATC temperature compensation, IP68 waterproofing (three-layer potting), RS485 output, and customizable interface/cable length, it’s built for industrial reliability.
Compact yet high-performing, it serves across sectors like environmental protection, agriculture, aquaculture, water treatment, chemical industry, and more—your go-to for accurate water quality analysis.
