General Description

The OMEGA®VA Series Vapor Actuated Thermometer is ideal for remote
readings, such as panel installations, with capillary lengths from 5 to 100
feet. This thermometer gives excellent readings above and below ambient
temperature and, being vapor actuated, is not subject to reading errors due
to either RFI/EMI interference or ambient temperature variations along the
capillary tube length.
