Vaisala's HM34 is a handy pocket-sized meter which provides fast and convenient spot-checks of relative humidity and temperature.

HM34 incorporates the remarkably accurate and stable HUMICAP® Thin-Film Polymer Sensor. The sensor is housed in an extendable probe that retracts back into the rugged plastic casing for storage, creating a compact and easy to carry device.

The automatic power-off function prevents the possibility of accidental battery discharge.
