Gann BL Compact TF-IR 2 Thermo Hygrometer

The Gann BL Compact TF-IR 2 has sensors for measuring both surface temperature via infrared and air temperature, relative humidity and absolute humidity, manufactured in Germany.

The Gann BL Compact TF-IR 2 has sensors for both surface temperature infrared measurements AND air temperature as well as relative humidity. This combination of the different measuring techniques enables the TF-IR 2 to be used for quickly and reliably assessing dew points and determining borderline conditions on surfaces such as walls, ceilings, floors as well as on window or door lintels.

The LCD display indicates three values with a reading resolution: 0.1 % or 0.1 °C.
The TF-IR 2 also has an automatic calculation of dew point temperature and equilibrium wood moisture content (EMC) along with display of absolute air humidity in g/m³ .

The plug-in TF stick measuring sensor is inter-changeable, and available separate purchase. Several of these sensors can be put in different places (environments) to aclimatise, therefore successive measurements in those places can be carried out more quickly, and settling times can be avoided (compared to a meter with fixed sensor).

An optional IANZ calibration test certificate is available for this model.

The Gann TF-IR 2 is covered by a 1 Year manufacturers warranty.
