Why Chilled Mirror Technology?

Chilled mirror hygrometers are considered the reference technology for humidity calibration because they measure dew point directly rather than estimating humidity from sensor response.

Advantages include:

  • Direct thermodynamic measurement
  • Excellent long-term stability
  • Minimal drift
  • High repeatability
  • Low uncertainty
  • Superior traceability

This makes chilled mirror technology the preferred reference for calibrating humidity and dew point instruments across industry and research.
