Product Description

Model BL784 Chilled Mirror Dew Point Meter

 

Chilled mirror dew point meter is a precise technique for determining the water vapor content is gases by directly measuring dew point or frost temperatures. Using this technique a metal mirror is cooled until it reaches a temperature at which a thin layer of condensation begins to form on it. The dew layer is detected optically, and the mirror is held at that temperature. The mirror temperature, measures with a PRT, is an accurate indicator of dew or frost point.

FEATURES

  • Dew point range -20to +85
  • Accuracy to ±0.20 dew point
  • Dynamic balance control for contamination
  • Simultaneously measures dew point, temperature, relative humidity, absolute humidity, specific humidity, enthalpy, vapor pressure and volume ratio (ppmV).
  • Real time data logging and curve display
  • MAX value and MIN value are recorded
  • AC or alternative DC power supply
  • MODBUS RTU and USB communication
  • 4 inch touch screen
