0...5000 ppm
Barometer: 600...1200 hPa
Measurement Uncertainty:
(1 minute after start)
CO2:
±35 ppm ± 3,7 % read value
Barometer: ± 3,5 hPa
Measurement uncertainty with 95% coverage probability in non con-
densating air.
In relative humidity below 80 %, at 0...35°C,
In relative humidity below 70 %, at 35...50°C, non aggressive gases
Sampling Interval:
CO2:
16 seconds
Barometer: Twice per second
Display Interval:
CO2:
16 seconds for the measured value.
Two prognostications in between, indicated by a * on
display. In stable conditions prognostications equal
measured value.
Barometer: Twice per second
Log Interval:
16 seconds - 2 hours. Pump can be set on or off. Set-
ting pump on turns it on 30 seconds before measure
ment is made.
