Heated Humidity Sensing Element for Radiosondes and Weather Balloons

  • Humidity

HMC03M

HMC03M is optimised for short response time even at very low temperature in the upper atmosphere. It combines on a silicon substrate a capacitive relative humidity sensor and a heating resistor (heater).

The heater is dedicated for fast recovery of the humidity sensor after condensation or icing. This leads to outstanding measuring performance in high-end weather observation.
