HMC03M |
Heated Humidity Sensor for Radiosondes |
|
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). |
รายละเอียด |
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. |
Key Features HMC03M |
Very short response time even at low temperature |
