List of the quantities:
T
: temperature
D
P
: differential pressure
RH
: relative humidity
I
: illuminance
T
D
: dew point
UVA
: UVA irradiance
T
W
: wet bulb temperature
UVB
: UVB irradiance
AH
: absolute humidity
UVC
: UVC irradiance
MR
: mixing ratio
P
UV
: proportion of UV present (µW/lumen)
PVP
: partial vapour pressure
CO
: carbon monoxide
P
ATM
: atmospheric pressure
CO
2
: carbon dioxide
(**)
One sample consists of all the quantities measured and calculated by the data logger at the same instant of acquisition. For example, the
model HD35ED1NAB measures four quantities and calculates five quantities (the derived humidity quantities) and one sample includes
one temperature measure, one CO measure, one CO
2
measure and six humidity measures (the relative humidity measure plus the five
derived quantities).
(***)
The minimum logging interval may be smaller if the data logger only stores some of the available quantities.
