Product Description Introduction This product is a new online dissolved oxygen sensor for water quality, developed independently by the Erun Group. It features high stability and precision, automatic temperature detection and compensation, and can accurately measure the conductivity and temperature of solutions. It is widely used for online monitoring of dissolved oxygen in water in aquaculture, petrochemicals, environmental monitoring, aeration tanks, water plants, power plants, sewage treatment, and industrial wastewater treatment. Product Features 1. LED display with intelligent Chinese/English menu operation.2. High-impedance preamplifier: High input impedance, noise immunity, and strong anti-interference capabilities.3. Multi-parameter simultaneous display: Simultaneously displays pH, temperature, two current outputs, and relay operating status.4. Output signal: Software selectable 0-20mA or 4-20mA output. User-defined password: Users can set or modify their own password to prevent unauthorized access and misoperation.Technical ParametersController Technical ParametersDisplayLEDSignal Output0-20mA (load resistance <750Ω)4-20mA (load resistance <750Ω)Power85-265VAC ±10%, 50±1Hz, power ≤3W; 9-36VDC, power ≤3WCommunication OutputRS485 Modbus RTUAmbient Temperature-10°C to 60°CRelative Humidity ≤90%Dimensions 144mm*144mm*130mm (H*W*D)MountingEmbedded (opening size: 138*138mm)Weight0.5kg Sensor technical parameters Measuring range0.00-20.00mg/LAccuracy±3mg/LResolution0.01mg/LTemperature measurement range 0.0-60.0°CTemperature sensor NTC22K (Pt100,Pt1000,NTC2.252K optional)Response time90%<90sCut-off flow rate>0.02 mg/LMaintenance intervalsReplenish or replace the electrolyte every 3-6 monthsand replace the membrane head every 6-12 monthsCalibration intervalOnce a monthPressure range0-2 barHousing materialABSConnecting threadM39*1.5Signal cable length5 meters or customizedElectrical connectionPin or BNC connectorMounting methodflow-throughIngress protectionIP68 Certifications Application
