Precision Calibration for High-Temperature Thermocouples

The Standard for High-Temperature Thermocouple Calibration

The Fluke 9118A Thermocouple Calibration Furnace delivers unrivaled performance and flexibility for demanding high-temperature calibration labs. Engineered for accuracy, reliability, and ease of use, the 9118A furnace helps you meet industry standards while improving productivity and lowering cost of ownership.

Key Features and Benefits of the Fluke 9118A

• Wide Temperature Range – Calibrate thermocouples from 300 °C to 1200 °C, covering most high-temperature industrial and laboratory applications.
• Flexible Configuration – Easily switch between tube furnace and isothermal block configurations to calibrate a wide variety of thermocouple types—accommodating both base-metal and noble-metal designs.
• Outstanding Uniformity and Stability – Achieve industry-best temperature uniformity and stability:
  • Axial uniformity: ±0.2 °C over a 60 mm zone at 1200 °C
  • Radial uniformity: ±0.25 °C at 1200 °C (isothermal block)
  • Temperature stability: ±0.1 °C or better across the full range
• Automated Setpoint Control – Boost lab productivity with programmable, automated temperature setpoint control. Supports up to eight setpoints, ramp rates, and dwell times—plus remote automation and data logging with the Fluke 1586A Super-DAQ.
• Non-Metallic, Contamination-Free Block – Ceramic alumina well and isothermal block minimize thermocouple contamination and reduce ongoing calibration costs.
