The HM70 Multi-Probe Hand-held Humidity and Temperature Meter with carrying case for Chambers and Incubators, 1%RH accuracy.
The Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70 with the HMP77B probe is designed for demanding humidity measurements in chamber and incubator applications. The probe, supplied with a 5 m (16.5 ft) cable, is ideal for difficult-to-reach areas and for on-site calibration of Vaisala's fixed transmitters.

The included chemical purge function maintains measurement accuracy in environments with high concentrations of chemicals. The sensor preheat function reduces measurement delays as it keeps the sensor dry when the probe is inserted into hot and humid processes.
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.
