Of the digital Psychrometergeber FPA 836-3P3 Ahlborn of two high-precision temperature sensors Pt 100 features. The sensors have a resolution of the meter 0,001 K without any linearization error. Thus, the dry and wet bulb temperature values are recorded accurately.
Based on the formulas of Dr. Sunday and taking into account the enhancement factor according to W. Bögel all humidity parameters are calculated exactly. In addition, the sensor factory adjustable in several ways, it is the error curve stored in the plug. Two galvanically isolated measurement inputs Psychrometergeber is connected to the precision instrument "Almemo 1036-2". In the measuring device, an air pressure sensor is installed. The measured air pressure is included in the calculations. Measuring range and accuracy can be increased significantly compared to older systems. Can be measured relative humidity, dew point, mixture, absolute humidity, vapor pressure and enthalpy.
