Telaire Vaporstat 9002

The Vaporstat™ is the first commercially available infrared humidity transmitter 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 Dewpoint. The Vaporstat™ is designed for direct in-duct or wall mounting. It can also used with any of Telaire’s mounting enclosures for duct or outside mounting.
