- Type K Measurement Grade Wire
- Special Limits of Error Accuracy
- 24 AWG Wire Size
- PFA Insulation
- Type K Calibration (Chromel/Alumel Conductors)

- Available in 25, 50, 100, 200 and 1,000 ft Spools
Our measurement grade thermocouple wire is ideal for constructing K type thermocouple sensors. This duplex wire consists of two conductors: one conductor constructed from Chromel alloy and the other conductor from Alumel alloy. Each 24 AWG conductor is individually insulated with a PFA coating with an additional layer PFA insulation over both conductors. PFA (Perfluoralkoxy) is a fluoropolymer with, temperature characteristics, chemical resistance and flexibility similar to Teflon®.
WR-TT wire is color coded according to ANSI standards and conforms to Special Limits of Error Accuracy specifications. It is offered in 25, 50, 100 and 200 ft spools.
Special Limits of Error Accuracy
American accuracy standards for thermocouples include Standard Limits of Error Accuracy and the higher accuracy class of Special Limits of Error. WR-TT wire conforms to Special Limits of Error Accuracy as defined by ASTM E230-ANSI MC 96.1.
Measurement Grade Wire at Extension Grade Pricing
There are two common grades of thermocouple wire: measurement grade wire and extension grade wire. Measurement wire is a higher grade wire used for manufacturing thermocouples and extension grade wire which is typically lower cost is used for extending thermocouples. Extension grade wire does not have the accuracy characteristics to be used for thermocouple manufacture. We have priced our measurement grade wire to be competitive with what many manufacturers charge for extension grade wire allowing our wire to be used to make thermocouples or as extension wire.
