1.
Determine:
– the sensor temperature (air temperature for the calibration type "air", water temperature for
the calibration type "air-saturated water")
– the altitude above sea level
– the current air pressure (
=rel. air pressure to sea level
) at the time of calibration. (If
undeterminable, use 1013 hPa.)
2.
Define:
– the saturation value
S
acc. to the first table
– the factor
K
acc. to the second table
3.
Determine:
–
L
= current air pressure in bar (1013 hPa=1.013 bar, if unknown)
4.
Calculate the calibration value

Example
• Air calibration at 18 °C (64 °F), altitude 500 m (984 ft) above sea level, current air pressure
1009 hPa=1.009 bar (15 psi)
• S = 9.45 mg/l, K = 0.943, L = 1.009
Calibration value C = 9.17 mg/l.
