HM70 Hand-held Humidity and Temperature Meter with carrying case for HVAC Applications, 1%RH accuracy
The Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70 with the HMP76 probe is designed for demanding humidity measurements in HVAC applications, especially in air ducts. It is also ideal for field checking and calibration of Vaisala’s fixed humidity instruments.
The HM70 also supports the use of Vaisala’s dew point, carbon dioxide and moisture in oil probes, making it a versatile investment applicable to several multi-parameter applications. Two probes can simultaneously be connected to the HM70.
The MI70 Link Windows® software and the USB connection cable form a practical way for transferring logged and real time measurement data from the HM70 to a PC.
The package includes:
- MI70 hand-held indicator
- HMP76 humidity and temperature probe: 0…100 %RH, -50…+120 °C (-58…+248 °F)
- Calibration
- Rechargeable battery pack and universal AC adapter
- USB cable
- Professional carrying case
- User’s Guide in English
