The Rotronic HygroPalm HP32 handheld humidity meter measures relative humidity, temperature, and performs extensive psychrometric calculations including dew/frost point, wet bulb temperature, enthalpy, vapor concentration, specific humidity, mixing ratio, vapor pressure, saturation vapor pressure, and saturation vapor density. The graphical display allows graphs and up to four simultaneous values.

Additional functions include spot measurements, time-programmable interval logging (1s to 24h), and min/max/average capabilities. Data transfer to PC via micro USB port, and the HP32 is compatible with HW4 software (LITE version included).
