The Vaisala HUMICAP HM34 hand-held humidity and temperature meter provides a fast and convenient way to accurately spot-check relative humidity and temperature. In measurement mode, the extendable probe slides out and measurements take only a few seconds. The HM34 meter includes a HOLD button which allows the user to retain an RH or T measurement until it has been noted or recorded.

The Vaisala HM34 will automatically switch itself off after three minutes of inactivity. The automatic POWER-OFF function prevents the accidental discharge of the battery.
