Fluke Calibration 9118A-ITB Thermocouple Calibration Furnace

Overview

The Fluke Calibration 9118A-ITB thermocouple calibration furnace is designed for accurate calibration of thermocouples across a wide temperature range from 300°C to 1200°C. The furnace features both tube furnace and isothermal block configurations, making it suitable for calibrating both base-metal and noble-metal thermocouples according to standards such as AMS 2750 and EURAMET cg-8.

Key Features

• Wide temperature range of 300°C to 1200°C covering most high-temperature applications
• Dual configurations: tube furnace mode for sheathed thermocouples, isothermal block mode for metal/ceramic-sheathed probes
• Ceramic alumina isothermal block accommodates up to four 6.35 mm probes
• Temperature stability of ±0.1°C or better with isothermal block
• Axial uniformity of ±0.2°C over 60 mm zone at 1200°C
• Radial uniformity of ±0.25°C at 1200°C with isothermal block
• Three independently controlled heater zones for temperature consistency
• Programmable control of up to eight setpoint temperatures with automated ramp rates
• Non-metallic ceramic block eliminates need for protective thermocouple sleeving
• Deep immersion depth of 365 mm with isothermal block, 350 mm without
• Redundant over-temperature cutouts and safety features
• RS-232 interface for remote control and data collection

Applications

• Calibration of base-metal thermocouples in sheathed or unsheathed configurations
• Calibration of noble-metal thermocouples with metal or ceramic sheaths
• High-temperature thermocouple verification per AMS 2750 and EURAMET cg-8 standards
• Multi-junction thermocouple testing and calibration
• Calibration of thermocouple wire spools and continuous materials
