Thermocouple Phidget<\/h1>\n

The Thermocouple Phidget connects directly to a thermocouple and allows you to measure an extremely wide range of temperatures! A thermocouple, or a thermocouple wire, is a device that is made of two different metals that are joined together. A thermocouple will produce a very small voltage that is temperature dependent. You can use a device like the Thermocouple Phidget to amplify the voltage and convert it into a temperature reading.The Thermocouple Phidget returns temperature in degrees Celsius (symbol: \u00b0C) and can be used in environments that a normal temperature sensor can’t (e.g. flames, liquids, ovens, etc.).<\/pee> <\/p>\n
