HM34 Pocket Size Relative Humidity Meter The Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM34 provides a fast and convenient way to accurately spot-check relative humidity and temperature.
Fast and easy-to-use
In measurement mode, the extendable probe just slides out. Normally, measurement takes 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. If no buttons are pressed for three minutes, the unit automatically switches itself off. This automatic POWER-OFF function prevents the possibility of accidental discharge of the HM34′s battery. After the measurement is completed, the probe is slid back into the meter casing. Between spot checks, the meter is normally stored in its carrying case.
