Introduction: Portable fluorimetric dissolved oxygen sensor, using the world's leading fluorescence life technology. RS485 output, support MODBUS, from maintenance, you can quickly and accurately measure the dissolved oxygen content, built-in temperature sensor, with automatic water temperature compensation. Can provide stable, highly reproducible, highly sensitive results of dissolved oxygen analysis. Determination principle: Fluorescence DO detector is based on the principle of quenching of active fluorescence in a specific substance in physics. The blue light emitted by a light-emitting diode (LED) shines on the fluorescent substance on the inner surface of the fluorescent cap. The fluorescent substance on the inner surface receives the excitation and emits red light. By detecting the phase difference between the red light and the blue light and calibrating with the internal calibration Value comparison, which calculates the concentration of oxygen molecules, after the temperature and pressure automatically output the final output value. Features 1 digital sensor, RS485 output, support MODBUS 2 no film, no electrolyte, no interference, no frequent calibration 3 does not consume oxygen, there is no flow rate limit 4 built-in temperature sensor, automatic temperature compensation Specifications: Range: 0 ~ 20mg / L or 0 ~ 200% saturation Accuracy: 1% Response time: 10 sec Sensor drift: <1% per year Temperature range: 0 ~ 50 ℃ Temperature accuracy: ± 0.2 ℃ Protection class: IP68 Maximum operating pressure: 6bar Sensor Interface: Support RS-485, MODBUS protocol Power Information: DC 6 ~ 12V, current <50mA Sensor size: Φ16 * 180 mm Probe cable length: 5m, the other customers optional 10m, 15m and 30m cable Calibration: One or two calibration Fluorescent cap life: to ensure the use of one year (under normal use) Sensor material: POM or stainless steel
