    Description: The KTA-259v5 Thermocouple Multiplexer Shield is designed to easily allow multiple high temperature readings with an Arduino control board. With the new version there are multiple advantages over the old KTA-259, namely, wider temperature range including below 0°C, higher accuracy, higher resolution and ability to use more thermocouple types (dependent on model).

    Screw terminals are provided for thermocouple connections as thermocouple wires can not be soldered.

    Note: The board ships as pictured, without Arduino headers. You can use standard brea-away headers, or the stackable headers. The board accepts both standard headers and R3 headers.

    Uses:
      • Automotive – Engine, Exhaust and Brake temperatures are higher than most temperature sensors can handle, but within the range of Thermocouples.
      • Ovens, Furnaces and Kilns – At temperatures where other temperature sensors will not operate.
      • Freezer or Cryogenic monitoring – Where temperatures are well below 0°C.
      • Chemical Processes – Where corrosive chemicals may damage probes or reach high temperatures thermocouples are more readily available for such processes.
      • Multi-Zone Temperature Monitoring, Data Acquisition or Logging Systems– With cheap readily available thermocouples.
