Thermocouple and RTD Wire

SERV-RITE thermocouple wire and thermocouple extension wire have been recognized for premium performance and reliability. All stock and custom wire is manufactured in Watlow's plant where materials, manufacturing equipment and quality controls are carefully selected to ensure superior uniformity. Watlow offers popular wires as well as custom manufactured wire using alloys and insulation types to meet specific application demands.

All SERV-RITE thermocouple wire and thermocouple extension wire is manufactured under rigid quality controls following ISO 9001 standards. In addition, all electromotive force (EMF) versus temperature calibration procedures follow one or more of the following standards:

  • ASTM E 207
  • ASTM E 220
  • AMS 2750

All testing has NIST traceability. Unless otherwise specified, all SERV-RITE thermocouple wire and extension wire are supplied to meet standard tolerances of ASTM E 230. Special tolerances are also available.
