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.
