Note: Assembled version comes with headers pre-soldered to the board.
Screw terminals are provided for thermocouple connections as thermocouple wires can not be soldered.
- 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.
- 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.
- Add up to 8 Thermocouples to an Arduino
- Cold Junction Compensated Output
- K, J, N, S, T, E or R Type thermocouples supported dependent on model
- 0.1 (2.54mm) Pitch Screw Terminals for Thermocouple connection
- 14-bit 0.25 °C Resolution
- Nominal ±2 °C Accuracy 
- Based on MAX31855 Cold-Junction Compensated Thermocouple-to-Digital Converter and ADG608 Multiplexer IC
- 13 x 8 Prototyping Area with Analog and Power pins
- Chip Select Pin Jumper Selectable means multi SPI shield compatibility
- Combine with SD card shield for powerful Temperature Logging
- Powered from 3.3V Arduino Pin, 5V compatible
