ZDO-02 dissolved oxygen+temperature sensor Introduction: ZDO-02 dissolved oxygen sensor is an intelligent dissolved oxygen electrode that uses RS485 communication interface and standard Modbus protocol. It can be widely used for dissolved oxygen monitoring in fields such as sewage plants, waterworks, surface water, aquaculture, and industry. Features: 1. Equipped with a corrosion-resistant shell and IP68, suitable for various harsh working conditions 2. Using optical methods without replacing dissolved oxygen membranes and electrolytes; This measurement has the characteristics of short polarization time and fast response, almost 3. It is not affected by dirt and speed 4. Low electrode drift, direct calibration in air without the need for zero adjustment 5. Equipped with NTC22K temperature compensation, the accuracy can reach 0.1 ℃. 6. Adopting RS485 communication interface and standard Modbus protocol for easy integration Technical parameters: Principle: Fluorescence method Range: 0-20.00 mg/L Resolution: 0.01mg/L Repeatability: ± 0.3mg/L Zero drift: ± 0.1mg/L Span drift:<45s Measurement accuracy: ± 0.3mg/L Response time: ± 0.1mg/L Temperature compensation accuracy: ± 0.3mg/L Actual sample comparison: ± 0.3mg/L Communication interface: RS485 (Modbus RTU standard protocol) Dimensions: D34mm, L205mm, 3-meter cable (customizable) Working conditions: 0 ℃~60 ℃ (without freezing), 0~4bar Working voltage: 12V/24V DC Voltage stability: ± ± 0.3mg/L Insulation resistance: ≥ 5M Ω
