Example
• Air calibration at 18 °C (64 °F), altitude 500 m (1650 ft) above sea level, current air
pressure 1009 hPa
• S = 9.45 mg/l, K = 0.943, L = 0.996, M=1.02
• Calibration value C = 9.05 mg/l.
Factor K in the table is not required if the measuring device returns the absolute air
pressure L
abs
(air pressure depending on altitude) as the measured value. The formula
for calculation is then: C = S . L
