DX 31 - Digital humidity / temperature sensor (e.g. for PRO D0x)
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).
