Calibration Services

TE Wire & Cable offers extensive calibration services to assure that our customers’ critical accuracy requirements are met. All calibrations are performed in our in-house laboratory, which is directly traceable to NIST (National Institute for Standards and Technology). All thermocouple wire in carefully calibrated, selected and matched to meet or exceed ASTM and ANSI initial calibration tolerance requirements (see below).

Calibration temperature capabilities are cryogenic –320°F (-196°C) and at any point from a low temperature of -110F (-79C) thru an upper temperature of 2400°F (1316°C). For specific point calibrations, special metal freeze point temperatures can be supplied: water triple point 32.018°F (.01°C), tin 449.47°F (231.93°C), lead 621.43°F (327.46°C), aluminum 1220.58°F (660.32°C), silver 1763.20°F (961.78°C), copper 1984.32°F (1084.62°C). Certified calibration test reports are available showing temperature deviations, correction factors or actual temperature readings.

Calibration reference standards, directly traceable to NIST, include base metal, Type S platinum, Type B platinum, 25 OHM platinum resistance thermometer and freeze point cells.

TE Wire & Cable’s calibration laboratory is ISO 9002 certified, and conforms to the requirements of MIL STD-45662A, ANSI/NCSL Z540, AMS 2750, ASTM E220, ASTM E207, ISO/IEC Guide 25

Products can be supplied to meet ASTM E230, ANSI MC 96.1, BAC 5621, ST 2155 and other customer special accuracy requirements.

TE Wire & Cable's calibration laboratory is also A2LA accredited to ISO/IEC 17025:2005, Certificate Number 2792.01.

In addition to wire,TE Wire & Cable offers calibration of thermocouples, sensors and RTD’s.

* Thermocouple material is normally supplied to meet tolerances above 0C (32F). If material is required to meet tolerances below 0C (32F), the purchase order must so state. Special selection of material is required.

** Suggested initial calibration tolerance. Requirements should be discussed between purchaser and supplier.

*** Copper vs. copper can be used as an extension for Type B thermocouples if the transition is below 100C (212F). Above 100C (212F), PCLW30-6 alloy should be used as the positive extension wire.
