The Rotronic HygroPalm HP31 handheld humidity meter utilizes a fixed probe to allow users to measure and log relative humidity, temperature, and psychrometric calculations. Psychrometric calculations 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 HP31 versatile 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 HP31 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.
