9118A Thermocouple Calibration Furnace

High performance furnace for thermocouple calibrations to 1200 ?C

The Fluke Calibration 9118A Thermocouple Calibration Furnace is a horizontal, open-ended tube furnace with a temperature range of 300 ?C to 1200 ?C. It is used for comparison calibration of noble and base-metal thermocouples by secondary high-temperature labs and instrument shops in industries such as aerospace, automotive, energy, metals, and plastics. The 9118A is the most accurate, reliable, and flexible furnace in its class, meeting the demanding requirements of high-temperature thermocouple calibration.
