Description
DX 310/311 is a digital combined temperature and relative humidity probe for the PRO D01 / PRO D05 handheld meters.
The probe supplies the following calculated quantities:
-
Dew point
-
Wet bulb temperature
-
Absolute and specific humidity
-
Mixing ratio
-
Specific enthalpy
-
Partial vapor pressure
-
Frost point temperature
-
Saturation vapor pressure above water and above ice
The probe is supplied factory-calibrated in multiple points for relative humidity and it is ready to use.
The probe can be optionally supplied with a DAkkS/ACCREDIA calibration certificate.
The calibration data are stored in the probe, allowing for interchangeability without the need for recalibration.
Equipped with 4-pin M12 connector and 2, 5 or 10 m cable (only DX311).
