HUMIDITY AND TEMPERATURE METER PROF DT-321S

PROF DT-321S is a high-quality digital temperature and humidity meter for checking indoor air quality, ventilation, and storage conditions. Measurements include temperature and relative humidity, from which dew point and wet-bulb temperature are automatically calculated. The device operates on a 9 V battery included in the package.

The meter can be used to determine humidity levels in different rooms of a building or the temperature and humidity of air coming from ventilation ducts. Measurements help to verify whether the ventilation system is functioning properly and can prevent, in the worst case, moisture condensation within building structures.

The device’s backlit display clearly shows readings and measurement results. The meter features Max Hold and Data Hold functions. Automatic power-off turns the meter off if it has not been used for approximately 15 minutes.
