This instrument has computer program controlled calibration, automatic temperature compensation, salinity correction, and atmospheric pressure adjustment functions, suitable for measuring oxygen content in aqueous solutions in various industries.

【 Working Principle 】

The DO-810 portable dissolved oxygen meter adopts ultra-low power microcontroller for measurement and control, and uses fluorescence method for measurement. It has the advantages of stability, reliability, simple and convenient operation, etc; This instrument can indicate the measurement results in two units of dissolved oxygen content, namely oxygen concentration (mg/L) and oxygen saturation percentage (%). In addition, it also measures and displays the temperature (℃) of the measured medium.

Table 1 Saturation Content of Oxygen in Water at Different Temperatures（Saturation: When the saturation is 100%）

Note: Saturated oxygen needs to be exposed to air in water using an aerator pump for 15 minutes, and the water after removing the aerator pump is saturated. If conditions do not permit, it can be assumed that the air is in a saturated oxygen environment.
