Page 3: Overview
1 Over view Thank you for purchasing Sanxin DO8500 Portable Optical Dissolved Oxygen Meter. The DO8500 measures dissolved oxygen in water using luminescence technology through an optical sensor and displays data using advanced intelligent instrument. Compared to conventional electrochemical dissolved oxygen meter, the DO8500 is more accurate and stable, easier to use and most cost-effective portable optical dissolved oxygen meter. -

Page 10: Sensor Cap
4.3 Sensor Cap (A) The sensor cap is an important part of the optical DO probe. The surface coating of the cap cannot be scratched or mechanically worn. Otherwise, the life of the sensor cap will be reduced or the probe will be damaged. Please pay special attention to it when using the probe. -
Page 11: Air Pressure Compensation
5.4 Air Pressure Compensation The instrument has automatic air pressure compensation function. The instrument has been performed the air pressure calibration before it leaves the factory. So generally users do not have to calibrate the air pressure. If necessary, calibrate it according to standard value measured by aneroid barometer. -
Page 12: Calibration
(B) Since salinity calibration is done by factory before delivery, so it is not necessary to perform salinity calibration during initial use. Only make salinity calibration when replace with a new electrode, or when the electrode is unused for long time. (C) For auto salinity compensation, should connect salinity probe, As shown in figure-14, user can fit DO probe and salinity probe together into the clip to measure simultaneously. -
Page 13: Special Notes For Calibration
6.3 Special Notes for Calibration (A) Please note that the closer the temperature of the sample solution to the calibration solution, the more accurate readings.So, it is recommended that the oxygen saturation calibration to be performed according to section 6.1 before use every day. (B) Drying of the surface coating of the sensor cap can adversely affect the stability of the measurement. -
