The 330 Air Humidity Meter is ideal for rapid measurement of ambient temperature and humidity. The precise Air Humidity Meter also allows the dew point (dew point temperature) to be determined. The Air Humidity Meter is equipped with an easy to read display and has a large memory (16,000 values) for recording the measured values.
