Abstract

A dew point hygrometer that adapts the primary measurement capability of the optical, chilled-mirror hygrometer to industrial requirements has been introduced by the Environmental Equipment Division of EG&G.

The new Model 440 hygrometer is a compact, portable unit providing continuous direct reading of dew point, with automatic self-standardization and National Bureau of Standards traceability. It features a broad operating range, rapid response and linear output. The instrument uses the same high-precision optical technique employed in EG&G laboratory hygrometers, which are often used as standards and calibrators.
