Advantages of Chilled Mirrors in the Validation of Climatic Chambers

• Low drift measurement of dew/frost points and temperature
• Automated gas sampling at temperatures up to 100 °C
• Probe format chilled mirrors for direct insertion into the chamber working volume
• Self aspirated measurement head option
• Simultaneous measurement of temperature to permit calculation of relative humidity
• Fully self contained and easily transportable
• Integrated calibration verification function to allow on-site verification of instrument performance
