Hydromette BL Compact RH-T

Enthalpy
Enthalpy (En) is a measure of the energy content of air-water
vapour mixtures, in kJ per kg.
4.2 Measuring the Temperature
Handling
The device is only suitable for measuring the air temperature (and
the rel. air humidity), not for recording the temperature of solid
materials and liquids. For particularly precise measurements,
particularly for temperatures under +10 °C or above +40 °C, or for
significant differences between the temperature of the sensor or
measuring device and the surrounding atmosphere, the device
should be exposed to the surrounding atmosphere of the
measurement location for approx. 10-15 minutes or until the
temperature has equalised. The measuring range of -40 °C to +80
°C only applies to the sensor tip of the electrode (length of the
protective/filter cap). The measuring device may only be exposed
to temperatures above 50 °C for short periods. False
measurements can arise from shielding with body parts (e.g. hand)
as well as blowing or speaking/breathing in the direction of the
sensor.
The setting time of the air temperature sensor in moving air is
approx. 3 minutes for 90 % of the temperature difference.
The air temperature sensor adapts to the surrounding temperature
even when stored (not switched on).
