Calibratable Temperature-Humidity Meter with Excel-formatted Data Logging SD Card


Calibratable Temperature-Humidity Meter with Excel-formatted Data Logging SD Card

The #DTH3007SD is ideal for tracking and logging the temperature and/or relative humidity of any fluid—including the dew point and wet-bulb temperature of ambient air. The instrument can also measure and log surface temperatures using a Type "K" or "J" thermocouple probe.

    What is Dew Point?

    In simple terms, the dew point (dew point temperature or dewpoint) is the temperature at which a given concentration of water vapor in air will form dew. More specifically it is a measure of atmospher...
