- Measuring range: RH: 0 ... 100 % Temperature: -50 ... +160 ˇăC
DX 310/311 is a digital combined temperature and relative humidity probe for the PRO D01 / PRO D05 handheld meters.
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).
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 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).
