RMZN600-A&RMZN507-A Portable Dissolved Oxygen Meter

Product introduction

      RMZN507-A portable dissolved oxygen sensor is independently developed, using the international leading fluorescence lifetime technology, based on the principle of the quenching of active fluorescence by specific substances in physics. The significant advantages of the fluorescence method for measuring dissolved oxygen are that there is no oxygen consumption,no flow rate limit, no preheating, no electrolyte, no maintenance and frequent calibration, and the response time of the sensor (T90) is as low as 20 seconds, far better than the national standard requirements.

     RMZN600-A&RMZN507-A portable dissolved oxygen detector, with automatic temperature, pressure compensation, salinity manual input compensation function; Support automatic dissolved oxygen detection valueLock, support setting filtering mode;The dissolved oxygen detection has high accuracy and stability, and can be used in unstable water conditions such as aeration tank and sewage plant with higher effect.

    RMZN600-A multi-functional handheld instrument independently developed. Instrument with operating keyboard and backlight display, simple interface, comprehensive functions, simple operation, support most sensors plug and play, automatic identification, using the instrument can easily perform data measurement, data storage, parameter setting, sensor calibration and other functions,and support data export; The pursuit of high cost performance is our consistent pursuit.

Product operation

    The fluorescence dissolved oxygen sensor is based on the principle of quenching active fluorescence by specific substances in physics. The blue light emitted by a light-emitting diode (LED) is irradiated on the fluorescent substance on the inner surface of the fluorescent cap. The fluorescent substance on the inner surface is excited and emits red light. By detecting the phase difference between red light and blue light, and comparing with the internal calibration value, the concentration of oxygen molecules is calculated. The final value is automatically compensated by temperature and air pressure.
