Description
Overview
The 9118A is a high-temperature calibration furnace designed for thermocouple calibration according to standards such as AMS 2750 and EURAMET cg-8. It offers a temperature range of 300°C to 1200°C and operates in two configurations: as a tube furnace for base-metal thermocouples or with an isothermal block for metal- and ceramic-sheathed thermocouples with higher accuracy requirements.
Key Features
- Temperature range of 300°C to 1200°C covering most high-temperature applications
- Flexible configuration: operates with or without an isothermal block for different thermocouple types
- Best-in-class temperature stability of ±0.1°C or better across the full temperature range
- Axial uniformity of ±0.2°C over a 60 mm zone at 1200°C with isothermal block
- Radial uniformity of ±0.25°C at 1200°C with block; ±0.5°C without block
- Three actively controlled heater zones for minimal axial temperature gradients
- Non-metallic ceramic alumina block and well to minimize thermocouple contamination
- Deep immersion depth of 365 mm with block or 350 mm without block
- Automated setpoint control for up to eight temperatures with programmable ramp rates
- Proprietary controller available in nine languages
- RS-232 interface for data acquisition system integration
- Redundant over-temperature cutouts and safety controls
Applications
- Calibration of base-metal thermocouples in braided fiberglass or PTFE sheathing
- Calibration of noble-metal thermocouples in metal or ceramic sheathing
- Calibration of multi-junction thermocouples
- Testing of thermocouple wire spools
- Quality assurance and standards compliance testing
