Thermocouple Thermometers
Commercial and industrial temperature sensor and probe capabilities vary with accuracy, speed and range of measurement. Thermocouple thermometers can measure a wide range of temperature because they are made of two wires, each a different alloy, that are welded together to form the thermocouple. The thermocouple produces a voltage that can be measured as temperature. The configuration of these thermometers is simple and therefore lends itself to many different mechanical designs, from tiny to rugged, and for quick reads on air or gas sensors. Accuracy varies with thermocouples but the better ones can measure within a few tenths of a degree. They can be used for general purpose temperature reading, high-temp, penetration (such as for food), surface reading, and wire reading. For more on temperature measurement see our temperature probes.
