H813 Dew Point Hygrometer

H813 Dew Point Hygrometer

A complete self contained dew point hygrometer that allows rapid and repeated measurement of the dew point of air using the classic chilled mirror method.

A small air sampling pump draws air from either the laboratory or a remote location through the sensing chamber. The temperature at which water vapour condenses on the mirror is recorded together with the ambient dry bulb temperature using the thermometers supplied.

Together, the measurements allows students to determine the condition of the sampled air either by calculation or using the psychrometric chart supplied.

The unit is complimentary to the Hilton Air Conditioning Laboratory Unit A660 and the Bench Top Cooling Tower H893.
