Example
• Air calibration at 18
˚
C (64
˚
F), altitude 500 m (1650 ft) above sea level, air pressure 1009 hPa
(405 inH
2
O)
• S = 9.45 mg/l, K = 0.943, L = 0.996
Calibration value C = 8.88 mg/l.
You do not need factor K from the table if your device returns the absolute air pressure L
abs
(location-dependent air pressure) as the measured value.
Thus, the formula for calculation is: C = S
