DVT-07c Aspiration psychrometers
DVT-07c aspiration psychrometer is used to measure accurately relative humidity and air temperature.
The principle of measuring is psychometric. In other words, it measures temperature of dry and wet thermometers with forced blowing.
The design of the probe is collapsible. It's available to exchange easily water in a container, to exchange a cord, to withdraw the probe with the industrial head to execute calibration.
DVT-07c operates at temperature up to 75°С. There is no impact of condensation that's gathering on probe's enclosure.

D-IT Meter
It allows to measure humidity and temperature of air using DVT-07c aspiration psychrometer with 2 x Pt1000 of nominal resistance. The device calculates relative humidity by difference of measurings of dry and wet thermometers taking into account the blowing. The meter has seven-segment indication of humidity and temperature, one relay output for alarm and RS485 output to transfer data. There are single, dual, quad channel models, that allow to connect simultaneously from one to four DVT-07c aspiration psychrometers.
