Arduino Thermocouple Multiplexer Shield (K - MAX31855K) (With Headers)

Description

Note: This version comes with headers pre-soldered to the board. Please allow 24 hours for shipment.
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.
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.
