The temperature-humidity meter with dew point is designed to check environmental conditions before and during painting operations, primer application and surface treatments. It measures ambient temperature and relative humidity, also displaying wet-bulb temperature and the dew point.
During the preparation and application of a coating, air temperature and humidity can affect operating conditions. Dew point measurement makes it possible to identify the temperature at which moisture in the air may begin to condense on a colder surface. This value therefore provides a useful reference for assessing the environment before carrying out activities that are sensitive to the presence of condensation.
The temperature-humidity meter brings together the main environmental parameters useful for checks before painting in a single instrument. Ambient temperature and relative humidity help describe the conditions in the working area, while the dew point completes the assessment when the risk of condensation needs to be considered.
Wet-bulb temperature is a further parameter available on the display. It expresses the cooling effect produced by water evaporation in the air and depends on ambient temperature and relative humidity. Together with the other values, it helps provide a more complete picture of the detected environmental conditions.
The Hold function keeps the measured value displayed, which is useful when the measurement needs to be recorded or several points in the working area need to be compared. The Max/Min functions make it possible to recall the maximum and minimum values recorded during the check, making it easier to compare environmental conditions at different times or in different areas of the same department.
Its portable and compact design makes the instrument practical for checks in production departments, on worksites, in workshops, in painting booths and in surface-preparation areas.
When temperature and humidity need to be checked at less accessible points, the temperature-humidity meter with external probe can be selected. For direct environmental checks with an integrated sensor, the compact model in the same range is available. If, in addition to air parameters, the contact temperature of a surface also needs to be measured, the two-channel temperature-humidity meter with K-type probe may be more suitable.
Calibration report available on request, to accompany the temperature-humidity meter with metrological documentation useful for internal checks and for monitoring its status over time.

FAQ – Temperature-humidity meter with dew point
What does a temperature-humidity meter with dew point measure?
The instrument measures ambient temperature, relative humidity, wet-bulb temperature and dew point temperature.
What is the dew point?
The dew point is the temperature at which moisture in the air reaches saturation and may begin to condense. It is a useful value for assessing environmental conditions before activities that are sensitive to the presence of moisture.
Why is the dew point useful in painting applications?
In painting operations, the dew point helps assess the risk of condensation on surfaces. Knowing this parameter together with temperature and relative humidity makes it possible to check environmental conditions more carefully before applying a coating.
What is the difference between dew point and wet-bulb temperature?
The dew point indicates the temperature at which moisture in the air may begin to condense. Wet-bulb temperature, on the other hand, expresses the cooling effect caused by water evaporation and depends on ambient temperature and relative humidity.
What is wet-bulb temperature used for?
Wet-bulb temperature expresses the cooling effect that occurs when water evaporates in the air. The value depends on ambient temperature and relative humidity: in drier air, it tends to differ more from the ambient temperature. It therefore helps complete the assessment of environmental conditions together with the other two parameters.
Can the temperature-humidity meter be used in painting booths?
Yes, it is suitable for checking temperature, relative humidity and dew point in painting booths, preparation areas and environments where primers, paints or other coatings are applied.
What are the Hold and Max/Min functions used for?
The Hold function keeps the measured value displayed. The Max/Min functions make it possible to recall the maximum and minimum values recorded during the check.
When is a temperature-humidity meter with external probe useful?
A model with an external probe is suitable when the measuring point is less accessible or when the sensor needs to be kept separate from the instrument body.
When is a temperature-humidity meter with a K-type probe needed?
A model with a K-type probe is suitable when, in addition to ambient temperature and humidity, the contact temperature of a surface or component also needs to be measured.
Is a calibration report available for the temperature-humidity meter?
Yes, a calibration report is available on request.
