The 4x Thermocouple Phidget is a thermocouple interface. It amplifies the signal from a thermocouple and provides a clean, stable digital reading for your application.
After connecting the interface to a computer through a VINT Hub Phidget, you can measure up to four thermocouples. Measurements can be returned as temperatures in degrees Celsius or as a voltage.

You can connect up to four J,K,E or T type thermocouples to this Phidget. See the product page or data sheet for the thermocouple to determine which end plugs into the positive terminal on the Phidget. If you're not sure which end is which, it won't harm anything to try both configurations to determine which one is right. If the thermocouple is hooked up backward, you'll get erratic readings and the temperature will decrease when it should be increasing.
