Hydromette BL Compact RH-T flex 350

The BL Compact RH-T flex 350 is an accurate thermo-hydrometer designed for fast measurements of the relative humidity and air-temperature.
By means of programmed sorption isotherms weight/mass percent can be determined for diverse building and insulating materials as well as for hard and soft wood.

Due to its thin sensor tube the measure meter is suitable for a large area of applications. These include, for instance, analyses, expertise, the dehumidification industry and the structural duhumidification. Also the checking of whether building materials are ready for finishing for floor and wood covering can be counted among the areas of applications.

Because of the thin sensor tube (goose neck) measurements at locations that are hard to access can be conducted fairly easy and incomplex.

Three different measured values, which are clearly displayed, can be indicated simultaneously, e.g. the combination of relative humidity, air-temperature and dew point.

The device is delivered fully equipped with battery and plastic box.
