Air Humidity Meter 555
The 555 Air Humidity Meter has been developed to take rapid measurements of humidity and temperature. The Air Humidity Meter also offers a calculation of dew point and information about wet bulb globe temperature. Thus you can, for example, prevent mould during the transport and storage of food. Also, the instrument is of benefit in the construction sector, such as in the determination of condensation on walls. With its compact dimensions, the Air Humidity Meter is particularly suitable for measurement on site.
