3. Determine:
•
L =
[rel. air pressure at calibration] : [1013 hPa]
•
M
=
1.02 for calibration in air
M
=
1.00 for calibration in air-saturated water
4. Calculate the calibration value:
Calibration value = S • K • L • M
Example:
•
Air calibration at 18°C, altitude 500 m above sea level, air pressure 1022 hPa
•
S = 9.45 mg/l, K = 0.943, L = 1.0089, M = 1.02
Calibration value = 9.17 mg/l
Table 1:
Saturation value S as a factor of temperature
(taken at an air pressure of 1013 hPa)
Table 2:
Correction factor K as a factor of mean altitude
(above sea level)
