Dew Point logger sensor NUL-245

Dew Point logger sensor


This sensor measures temperature and humidity in a volume and gives the temperature below which the water vapor in that volume of air (at a constant barometric pressure) condenses into liquid water (the dew point).

  • Used in the fields of Biology, Exercise Science, Environmental Science, Earth Science, Weather Science, Botany, Entomology, etc.
  • The sensor relies on two different sensors to accurately determine the dew point of an environment: a temperature and a humidity sensor. The internal temperature sensor uses a thermistor which changes its resistance according to temperature change. The internal humidity sensor utilizes a dielectric polymer to absorb water molecules.
  • The sensor is pre-calibrated at the factory.
  • Experiment duration: 1 second to 31 days.
