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