          詳細介紹

          HMC03M(用于無線電探空儀和氣象氣球濕度傳感器)詳見產品規格書

          HMC03M Heated Humidity Sensor for Radiosondes and Weather Balloons

          HMC03M is optimized for short RH response time even at very
          low temperature in the upper atmosphere. It combines on a silicon
          substrate a capacitive relative humidity (RH) sensor and a heating
          resistor (heater).
          The heater is dedicated for fast recovery of the humidity sensor
          after condensation or icing. The construction with the heater
          positioned all around the RH sensor grants uniform temperature
          throughout the HMC03M structure, which leads to outstanding
          measuring performance in high-end weather observation.

          Features:

          Very short RH response time at low T
          High sensitivity
          Fast recovery after condensation or icing due to sensor heating
          High accuracy thanks to outstanding T uniformity within HMC03M
