0.1 °C accuracy in the following sizes: 30ga, 36ga, 40ga, 44ga
Many insulation materials available
Most competitors' thermocouple wire used in the manufacture of sensors is "Special Limits" wire which, to meet NIST standards, must be accurate to 0.5 °C. This means that even with the most sophisticated electronics, the best possible accuracy for the system is 0.5 °C.
Physitemp wire is made and tested to more stringent standards and is guaranteed accurate to 0.1 °C in the range of 0-50 °C.
It is, therefore, five times more accurate than "Special Limits" wire. It is intended for applications where high accuracy is essential but where the low cost of thermocouples is important.
Wires are also available in rolls of 50' or larger quantities. Furthermore we weld thermocouples and/or provide custom sheaths on request. If you require wire with a different gauge or insulation than listed below please don't hesitate contacting us as we might obtain them for you as well.
