EC Meter Online Chemical Analyzer,Monitoring TDS/Resistivity/Conductivity/Temp,for Water,Hydroponics,RO System and Food Industry

EC Meter Online Chemical Analyzer for continuous monitoring of conductivity (EC),TDS,resistivity, and temperature in liquid solutions.Designed for stable trend tracking in control cabinets and process systems,this water quality monitor helps operators and automation systems keep solution quality consistent over time—especially when EC and temperature drift can impact product quality or process efficiency. Built for integration, the conductivity controller supports 4–20 mA signal output and RS485 Modbus-RTU communication for PLC/SCADA monitoring,logging,and routine control.Relay alarm/control functions enable high/low setpoint actions with warning delay,helping reduce false triggering in real-world operation.To improve reliability in unattended duty,the analyzer also supports practical settings such as buzzer and LCD backlight options,password access,and watchdog protection. Flexible probe matching is supported through multiple electrode constants, allowing you to select the right conductivity electrode for low to high conductivity ranges. Temperature compensation (manual or automatic with compatible temperature sensors) helps maintain consistent readings across changing operating conditions. Typical applications include wastewater treatment and water treatment plants, RO system monitoring, fertigation dosing control, hydroponics nutrient solution management, and process-water loops in the food industry (for process water monitoring, not direct food testing).
