Portable humidity and temperature measurement

Portable humidity and temperature measurement.

This handheld device can be used in combination with any of the HygroClip HC2 probes, using AirChip technology to offer outstanding accuracy and repeatability performance. The range of HC2 probes, and the ability to calculate humidity in a variety of different scales (see below), allows the HygroPalm22-A (HP22-A) to be extremely versatile.

Quick spot checks of processes or controlled areas can be made to ensure humidity and temperature requirements are within acceptable limits.

This portable unit can be used to decrease measurement costs by using a single instrument to monitor several locations, when permanent monitoring is either not required or cannot be justified.

The HP22-A can also be used to cross-check permanently installed systems.

For an option with an internal data logger or two probes connected simultaneously see the HygroPalm23-A

The HP22-A calculates humidity in a choice of humidity scales:

Relative humidity in %
Temperature in °C or °F
Absolute humidity in Kg/m3
Dew point/frost point in °C or °F
Wet-bulb temperature in °C
Enthalpy in KJ/Kg
Specific humidity in g/Kg
Vapour concentration in g/m3
Mixing ratio in g/Kg
Saturation vapour pressure in hPa
Partial water vapour pressure in hPa
Water vapour saturation pressure in hPa
Water vapour partial pressure

Sensor Technology

Advanced sensor diagnostics can be enabled using the AirChip3000 technology enbedded in the HygroClip2 (HC2) probe. Up to 2,000 measured values can be stored in the probe with the ability to set alarm limits, configure measuremnent intervals and download the data to HW4 software.
