1 Introduction
1.1 Description
The Hydromette BL Compact RH-T is a precise thermo-
hygrometer for quick measurement of relative air humidityand air
temperature. Using programmed sorption-isotherms, the weight
andmass percentages canbedetermined for various building and
insulationmaterials, as well as hardwoods and softwoods. Due to
the thin sensor tube (5.5 mm diameter), it is eminently suited to
moisture analyses, damage evaluation, dehumidifying buildings
and checking the readiness of floor and wall coatings. Additional
features includesingle-handedoperation,integratedmeasurement
probe and a 3-line LCD screen for the simultaneous displayof air
humidity, air temperature and dew point.
The Hydromette BL Compact RH-T flex T model has a flexible
sensor tube (6.5 mm diameter, swan neck) and is therefore
excellent for measurements of points that are difficult to access.
