The Barfield TT1200A is the latest digital turbine temperature test set, with many new features:

• Microprocessor-based
• Backlit alphanumeric display
• User prompts
• °F and millivoltage display
• Temperature range to 1,372°C
• 4 resistance and 4 insulation ranges and power comes from standard "C" batteries for all functions

This completely self-contained, battery-powered unit is housed in a new high-visibility ruggedized enclosure. The turbine temperature unit is designed with sufficient accuracy and range to be able to test the newest digital and glass cockpit indicators with simplicity of operation, direct reading, and multi-function versatility.

The TT1200A is specifically designed to accomplish all requirements for testing the aircraft Chromel-Alumel (K type) turbine temperature measuring systems. The Test Set can measure resistances down to 0.001W, measure insulation up to 200 MW, perform indicator run-outs with a resolution of 0.1°C or 1°C and a range of 1372°C, and can also display the equivalent °F or millivoltages and may be used as a master indicator as well.
