Description

The TF58 and TF59 expansion thermometers are temperature measuring instruments in plastic cases with drum dials.

An expansion thermometer measures temperature based on the principle of thermal expansion. This principle involves the expansion of materials when heated and their contraction when cooled.

The design of each model varies depending on indication accuracy, scale length, dimensions, mounting type, and panel frame design.

Special features

  • Temperature indication independent from measuring point
  • With capillary
  • Universally applicable
  • Plastic case for panel mounting
