Overview
SMART SENSOR AR8210 + pen dissolved oxygen meter is a professional measuring instrument with high accuracy, stable and reliable operation and easy portability. It can accurately measure the dissolved oxygen value of water quality and display the temperature of the measured water quality, and is widely used in agriculture, industry, aquatic products, laboratories, domestic water and other fields.
Features
1. High accuracy, stable and reliable work
2. Portable design
3. Color screen display interface
4. With automatic temperature compensation function
5. Support data retention function
6. Self-Adjustment
7. Support unit conversion (° C/° F)
Principle
Electrode measurement of dissolved oxygen content in water, temperature compensation technology to ensure measurement accuracy. Electrode needs to be filled with a special Electrode liquid and connected to the instrument, after polarization treatment for measurement.
Applications
Agriculture, industry, aquatic products, laboratories, domestic water
Steps
1. Remove Electrode film sleeve and add 3/4 Electrode filling solution to ensure that no bubbles exist
2. Screw the Electrode film sleeve onto the Electrode until tightened to ensure that the film adheres to the surface of the gold cathode
3. Connect Electrode to the instrument and use it after 30 minutes of power-on polarization
4. Use two-point calibrating, prepare anaerobic water and saturated dissolved oxygen water for calibrating
5. If the tested water sample contains salinity, the salinity setting needs to be carried out (0.0~ 45)
If not measured at sea level, set atmospheric pressure (101.3~ 79.9KPa or 760~ 600mmHg)
Notice
• Electrode that has just left the factory can only be used after adding Electrode filler
• When adding Electrode liquid, make sure that there are no bubbles in the Electrode film sleeve
• If Electrode Filler Overflows, Dry Immediately
• Electrode needs to be polarized for 30 minutes before use
• If Electrode is inserted into anaerobic water or saturated dissolved oxygen water, the value does not change much, and the Electrode film sleeve and Electrode filling solution need to be replaced
• Salinity value needs to be set after Salinometer measurement
• Atmospheric pressure needs to be set after barometer measurement
