The Barfield TT1200A is a Digital Turbine Temperature Test Set. It is microprocessor based, completely self-contained, battery powered unit housed in a high visibility  ruggedized enclosure. It is designed with sufficient accuracies and range to be able to test digital and glass cockpit indicators with simple 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 0.001 ohms, measure insulation up to 200M ohms, perform indicator run-outs with a resolution of 0.1ºC or 1ºC and a range of 1372ºC. It can also display the equivalent ºF or millivoltages and may be used as a master indicator.

The TT1200A exceeds all of the operational capabilities of the popular Barfield TT1200A.

Features include:

• Microprocessor based
• Backlit alphanumeric display
• User prompts
• ºF and millivoltage display
• Temperature range to 1372º
• 4 resistance and 4 insulation ranges
• Power from common "C" batteries for all functions.
