REOTEMP’s Vapor Actuated Filled System Thermometers can be fitted into a large variety of temperature indicating applications. Manufactured to the highest standards, these instruments are ideal for remote reading. Vapor actuated thermometers, are not subject to indicator error due to ambient temperature variations along the capillary tube system, and will give excellent readings provided the measured temperature is above or below ambient temperature.

Note: Vapor instruments have progressive non-linear graduations, and are best read in the upper 2/3 of the dial range. Many ranges are available between -40°F and +450°F, and care should be exercised to select a range that will locate the operating temperatures within the upper 2/3 of the dial range.
