Altitude adjustment
Perform correction for correct measurement and calibration of dissolved
oxygen density at high altitude.
The saturated dissolved oxygen content is compared against the oxygen
content in the surrounding atmosphere. As the altitude increases, the air
pressure in the atmosphere is lowered and the saturated dissolved oxygen
content becomes smaller.
Example)
1013 hpa: Saturated dissolved oxygen content is 8.26 mg/L (25 ° C)
506.5 hpa: Saturated dissolved oxygen content is 4.13 mg/L (25 ° C)
When the air pressure is halved, the saturated dissolved oxygen content is
also halved.
Measurement at high altitude requires altitude adjustment.
This product adjusts by altitude (m) instead of atmospheric pressure (hpa).
