HondeTech - Model RS485 -5-in-1 Water Quality Sensor for PH, EC, Temperature, TDS, and Salinity

This advanced multi-parameter water quality sensor integrates the ability to measure five crucial parameters — pH, electrical conductivity (EC), temperature, total dissolved solids (TDS), and salinity — in a single highly compact form. Specifically engineered for installation in small pipelines, this sensor combines ease of installation with precise digital output using the MODBUS protocol via RS485. The unit supports secondary calibration for pH and EC measurements, ensuring sustained accuracy over long-term usage. It is versatile in connecting to various wireless data transmission technologies, including GPRS, 4G, Wi-Fi, LoRa, and LoRaWAN, providing real-time data access and enhanced remote monitoring capabilities. Designed for numerous application scenarios such as sewage treatment, drinking water quality assessment, and aquaculture, it is adaptable to diverse environmental conditions demanding rigorous water analysis.
