HMC03M – Heated Humidity Sensor for Radiosondes and Weather Balloons

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.
