How should I choose between thermocouples or thermistors?
Our type T thermocouple instruments have extremely high accuracies, in the order of 0.05 °C to 0.1°C under certain conditions. And our type T thermocouple instruments have measurement resolutions of 0.01 °C or better. Our type T instruments can be used to measure temperatures over the range -200 to +400 °C ( -328 to 752 °F). Thermocouples have no self heating and can be very small in size. Small thermocouples respond to temperature changes much faster than thermistors or RTD’s, which have more mass. And small thermocouples can be inserted in liquids or solids or attached to surfaces without disturbing the temperature field of the object that is being measured. Thermocouples are also available in hypodermic needles. And 40 gage bare wire thermocouples are only about 0.003″ (0.08 mm) in diameter. If you need higher accuracies, then our thermistor instruments can provide measurement accuracies from 0.01 °C to 0.002 °C, with measurement resolutions from 0.0001 °C to 0.0004 °C depending on
