LoRaWAN water quality total hardness sensor is a type of sensor used to test the total hardness of water (measured as CaCO3), with automatic temperature compensation function, low environmental impact, and high measurement accuracy. Connect to the LoRaWAN collector through an aviation connector to achieve wireless communication. Widely used for online automatic continuous analysis and detection of water quality hardness in industrial wastewater, surface water, drinking water, seawater, and industrial production process control.

ZW-TH-PR split-type online total hardness sensor uses patented PVC film Ca-Mg ion electrodes to measure water total hardness (as CaCO3) with 0~1000.0mg/L range and 0.1mg/L resolution, ±10% reading accuracy. Equipped with Pt1000 automatic temperature compensation, T90<60s, IP68 protection and 3/4NPT multi-installation mode. It supports RS485/ModbusRTU (optional 4-20mA) output, low power consumption, easy connection to PLC/DCS, and two-point calibration. The stable reference system extends electrode life, ideal for industrial water quality monitoring.
