HMC03M is optimized 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.
- Very short response time even at low temperature
- Fast recovery after condensation or icing due to sensor heating
- High sensitivity and outstanding linearity
