Elcometer 309 Digital Delta T Hygrometer
The Elcometer 309 Delta T hygrometer enables simple and rapid measurement of two critical climatic parameters in coatings: Delta T (TΔ): The difference between the surface temperature (Ts) and the dew point temperature (Td).
Delta T and RH MeasurementMeasures the difference between surface temperature and dew point (TΔ) as well as relative humidity in coatings.
A robust constructionDust- and waterproof, with fully sealed sensors, suitable for extreme conditions.
Limit value indicatorsThe screen displays pass or fail results graphically, accompanied by flashing red or green LEDs.
Retaining measurementsMeasurements can be frozen on the display with a single button press and then released.
