Description
Barometric pressure, pb, is an important variable to be measured for calibrating oxygen sensors in solutions that are equilibrated with air. The atm-standard pressure (1 atm = 760 mmHg = 101.325 kPa) has been replaced by the standard pressure of 100 kPa. The partial pressure of oxygen, pO2, in air is a function of barometric pressure, which changes with altitude and locally with weather conditions. The partial oxygen pressure declines by 12% to 14% per 1,000 m up to 6,000 m, and by 15% to 17% per 1,000 m between 6,000 and 9,000 m. An electronic pressure transducer is built into the OROBOROS Oxygraph-2k as a basis for accurate air calibrations in high-resolution respirometry. The warranty for the accurate calibration of the electronic baromemtric pressure transducer of the O2k expires after three years.
