The Vaisala HM70 Hand-Held Humidity and Temperature Meter is designed for demanding humidity measurements in spot-checking applications. It is also ideal for field checking and calibration of Vaisala's fixed humidity instruments. The Vaisala HM70 incorporates the latest generation of the Vaisala HUMICAP® Sensor. Vaisala HM70 is reliable and has better than ever long-term stability. Additionally, it has a sensor that copes well with chemical interference and provides accuracy that lasts in demanding conditions.

The Vaisala HM70's chemical purge option maintains measurement accuracy in environments with high concentrations of chemicals. The sensor preheat option reduces measurement delays as it keeps the sensor dry when the probe is inserted into hot and humid processes.
