Cold Mirror Dew Point Meter KST-V | High-Precision Analysis for N₂, H₂, SF₆
Working Principle
The cold mirror technology measures dew point by condensing water vapor onto a reflective surface when gas temperature drops below the dew point—the saturation temperature of water vapor in the gas. As dew or frost forms, diffuse reflection of incident light activates an electrical signal in the photosensitive device. The detection circuit transmits signal variations and temperature data to the control system, which uses intelligent algorithms to calculate and display dew point temperature (designated as frost point when below 0°C).
