Vaporstat 9002 Infrared Dew Point Sensor

Vaporstat 9002 Infrared Dew Point Sensor

 

The Vaporstat™ is the first commercial infrared dew point sensor that directly measures absolute humidity by counting the number of water molecules in air. The sensor display provides a user selectable display of grains/lb of dry air or °F dew point. The Vaporstat ™ is designed for direct in-duct or wall mounting applications and is compatible with all of Telaire's accessory enclosures. The Vaporstat ™ provides a similar performance to a chilled mirror, but is a fraction of the cost and requires considerably less adjustment and maintenance.

 


Features

Infrared Dew Point Offers:

  • A Break-Through in Low Cost Reliable Dew Point Sensing.
  • Measure Moisture Independent of Temperature Interference.
  • Direct Measurement of Dew Point Eliminates Stacked Errors Resulting From RH and Temperature Calculation.
  • Unprecedented 15-Year Sensor Life.
  • Non Interactive Sensing Technology That Can't be Poisoned or Saturated.
  • Can Be Field Calibrated to an Easy-to-Use NIST Reference Standard in Less Than 15 Minutes.
  • Advanced technology developed with the assistance of the: U.S. DOE, Desiccant Technologies Program, Oak Ridge National Laboratories.
