Portable humidity and temperature measurement with data logging.

This handheld instrument can be used in combination with up to two 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 HygroPalm23-A (HP23-A) to monitor both inlet and outlet variables to a process.

Quick spot checks of processes or controlled areas can be made to ensure humidity and temperature requirements are within acceptable limits. The data logging facility allows a time and date stamped record to be stored of the measured data.

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 can not be justified.

The HP23-A also includes all the features of the HygroPalm22-A and can also be used to cross-check permanently installed systems.

The HP23-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
