Example
• Air calibration at 18°C (64 °F), altitude 500 m (1650 ft) above sea level, air pressure 1009 hPa
(405 inH

O) =1.009 bar
• S = 9.45 mg/l, K = 0.943, L = 1.009
Calibration value C = 9.17 mg/l.

Note!
You do not need factor K from the table if your device returns the absolute air pressure L

(location-dependent air pressure) as the measured value.
Thus, the formula for calculation is: C = S
