Page 29: Application Notes
9 Application Notes 9.1 General Notes on Humidity / Air Temperature Measurement Humidity, also known as air humidity, is the water vapour content of the air. Like any other substance, air only has a limited capacity to absorb water. This limit is known as the saturation limit. Above the saturation point, the excess water content accumulates in the form of very fine water droplets (condensate). -

Page 31: Precautions
9.2.1 Precautions The sensor can be irreparably damaged by various mechanical or environmental influences. These include in particular: direct contact of the sensor with the fingers direct contact with solid or sticky materials or objects measurement in environments containing solvents, oil vapours or other high levels of contaminants storing the sensor in foam materials NOT provided by us removal from the drill hole too hastily. -
Page 32: Equilibrium Wood Moisture Content (Emc)
9.4 Equilibrium Wood Moisture Content (EMC) Equilibrium wood moisture content is the moisture content adopted by the wood when it is exposed to constant climate (constant humidity and constant temperature) for sufficiently long time. The device can simultaneously display relative humidity, temperature, and equilibrium wood moisture content. -
Page 33: Dew Point Temperature
9.7 Dew Point Temperature The dew point temperature is the temperature at which the air is saturated with water vapour. The relative humidity is then 100%. If this dew point temperature is undershot, the moisture contained in the air condenses on a component / surface. The dew point temperature is generally lower than the air temperature, except at 100% R.H. -
Page 34: Wet-Bulb Thermometer
9.9 Wet-Bulb Thermometer The wet-bulb temperature is the lowest temperature that can be achieved with evaporative cooling. The release of water from the damp surface is in balance with the ability of the surrounding atmosphere to absorb water and thus saturates the surrounding air with water vapour. Because of the evaporative chill, the wet-bulb temperature is dependent on the relative air humidity and lies under the air temperature. -
Page 35: Measuring The Relative Air Humidity In Building Materials
9.10 Measuring the relative Air Humidity in Building Materials The method for measuring the relative air humidity/equilibrium moisture content in screeds has been used for a long time in Great Britain and the Scandinavian countries. Compared to the non- destructive measurement or the resistance measurement, it is, however, more time-consuming and requires suitable drilled holes. -
Page 36: Drill Hole" Method
9.10.1 "Drill hole" Method For the measurement, a hole with a diameter of min. 7 mm or 8 mm (flex) and a depth of at least 40 mm is drilled. A sharp drill bit, a high impact rate and a low speed are important. If the drill hole is very hot, wait for the temperature to equalise before measuring. -
