Portable Optical DO Meter
1) Optical DO Sensor: 0~20mg/L or 0~200%
2) Free-Maintenance: no need to add electrolyte solution.
3) High stability, no need to regularly calibrate or replace the sensor cap.
4) High repeatability, no drift measured.
5) Simple operation, no agitation, no flow-dependent and accurate from dirt.
6) Automatic temperature and pressure compensation, plug and use.
7)Salinity compensation function: to test the sea water and a variety of salt solution dissolved oxygen.
Product Details
AM-P-ODO Portable Optical DO Meter with automatic temperature and pressure compensation, salinity manual input compensation function; It supports automatic locking of dissolved oxygen detection value and setting of filtering mode. The dissolved oxygen detection has high accuracy and stability, and can be used in unstable conditions of aeration tank, sewage plant and other water bodies with higher effect.The DO sensor adopts the internationally leading fluorescence lifetime technology, which is based on the quenching principle of specific substances to active fluorescence in physics. The remarkable advantage of this fluorescence method in measuring dissolved oxygen is that it does not consume oxygen in the measurement process, so there is no flow rate limit, no need to preheat electrolyte, no need for maintenance and frequent calibration. The response time of optical dissolved oxygen probe is as low as 20 seconds, making the measurement of dissolved oxygen more accurate, more stable, faster and more convenient.
