The Perkin Elmer TAC 7/DX Thermal Analysis Controller is an intelligent microprocessor controller that links the computer to the 7 series thermal analysis modules. The TAC 7 has a high speed microprocessor for control of all functions. Two RS-323C communication ports, one analog control port and one digital port. The TGA 7's built-in diagnosis continuously monitor and analyze all system functions. The Perkin Elmer TAC 7/DX Thermal Analysis Controller has a high Balance Sensitivity that is thermally isolated from furnace. The fast cool down of this controller increases throughput.
