  • Indicates media temperature using a temperature-actuated liquid in the sensing element and a highly accurate, high quality pressure gauge
  • As the media temperature increases, the capillary fill fluid vaporizes, increasing pressure in the Bourdon tube to activate the movement and pointer for proper indication
  • Brass, stainless steel, or phenolic case
  • Dry or liquid filled
  • Bottom, back or lower back connected
  • The dial scale graduations are non-linear, therefore the highest degree of accuracy and readability is found in the upper half of the scale
