Almemo: Hygrometer, Dew Pt & Thermometer

Humidity measurement with very high resolution, precision,and linearity using Pt100 psychrometer.

Suitable as reference device in calibration laboratories and for quality assurance procedures.

A very high level of accuracy is achieved using the Pt100 psychrometer - a factory multi-point adjustment is made to optimise accuracy.

The Pt100 psychrometer is optimized by utilising high humidity levels over long periods of time.

Automatic atmospheric pressure compensation is made for pressure-dependent humidity variables by means of a digital atmospheric pressure sensor which is integrated in to the ALMEMO device.

Humidity calculations are based on the formulae of Dr. Sonntag and enhancement factors used are as per W. Bogel (correction factor fw(t,p) for real mixed gas systems) This substantially widens the measuring range and improves the accuracy of the humidity variable calculations.

Resolution parameters - temperature Pt100 0.001 K, - relative humidity 0.01%, - dew point 0.01 K

The humidity variables are calculated from the three primary measuring channels (real measurable variables). Dry temp.(°C), humid temp. (°C), atmospheric pressure (mbar).

3 humidity variables can be displayed simultaneously and are freely selectable.
Relative humidity (%), dew point (°C), mixture (g/kg)
Absolute humidity (g/m³), vapour pressure (mbar), enthalpy (kJ/kg)
