The Rotronic HygroPalm HP32 handheld humidity meter is the latest development in handheld measuring instruments for relative humidity, temperature and psychrometric calcualtions. Psychrometric calucations include dew/frost point (Dp/Fp), wet bulb temperature (Tw), enthalpy (H), vapor concentration (Dv), specific humidity (Q), mixing ratio by weight (R), vapor pressure (E), saturation vapor pressure (Ew) and saturation vapor density (SVD). The graphical display allows for graphs and up to four values.

Additional functions of the Rotronic HygroPalm HP32 handheld humidity meter include spot measurements, time programmable interval logging (1s to 24h) and min/max/average capability. The on-board memory capacity is 8 x 8,000 data points and data can be transferred to a PC via the micro USB port. The HP32 is compatible with HW4 software and the LITE version is included with the meter. The integrated 3.7V, 1000 mAh Lithium Polymer battery allows for up to 10 hours of use if the screen is always on or up to 48 hours of use when logging every 30 seconds with the screen off.

Rotronic HygroPalm 32 handheld humidity meters utilize HygroClip 2A and HygroClip 2 probes (sold separately) which are available in many models to suit specific applications, from simple plug-in probes for use with a handheld instrument or data logger to a more sophisticated cable probe for high temperature and other special applications.
