Electronics123.com, Inc. Arduino Thermocouple Multiplexer Shield (K - MAX31855K)

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.

Features:

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
