Optical oxygen meter SUP-DO700

4-20 mAdigital

SUP-DO700 Optical dissolved oxygen meter SUP-DO700 dissolved Oxygen meter adopts fluorescence method to measure dissolved oxygen.The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated. Features Resolution: 0.01mg/L,0.1%,1hPa Output signal: 4~20mA; Relay; RS485 Power supply: AC220V±10%; 50Hz/60Hz Product - Dissolved oxygen meter Model - SUP-DO700 Measure range - 0-20mg/L,0-20ppm,0-45deg C Accuracy - Resolution:±3%, Temperature: ±0.5℃ Pressure range - ≤0.3Mpa Calibration - Automatic air calibration,Sample calibration Sensor material - SUS316L+PVC (Ordinary Version), Titanium Alloy (Seawater Version) O-ring: Fluoro-rubber; Cable: PVC Cable length - Standard 10-Meter Cable, Max : 100m Display - 128 * 64 dot matrix LCD with LED backlight Output - 4-20mA(Max three-way); RS485 MODBUS; Rlay output(Max three-way); Power supply - AC220V, 50Hz,(optional 24V） SUP-DO700 Dissolved oxygen meter measures the dissolved oxygen by the fluorescence method, and the emitted blue light is irradiated on the phosphor layer. The fluorescent substance is stimulated to emit red light, and the oxygen concentration is inversely proportional to the time when the fluorescent substance returns to the ground state. Product Advantages Ø The sensor adopts new type of oxygen sensitive membrane,with NTC temperature compensated function,
