III-Vs Review

Keithley Instruments, Inc., said that its Metrology Services Group is now accredited to ISO/IEC 17025:2005, the single most important metrology standard for test and measurement, by the A2LA (American Association for Laboratory Accreditation).

This latest accreditation expands the list of Keithley certifications by industry-recognized standards for quality such as ISO 14001 and ISO 9001. The accreditation recognizes that Keithley's Metrology Services meet the

requirements of this international standard, demonstrating its technical competence to carry out very high-level calibrations that are essential for many of Keithley's instruments, which have measurement resolutions below 1fA or 10-15.

The scope of accreditation can be viewed at: http://www.a2la.org/scopepdf/2462-01.pdf.

Keithley's customers can expect ISO 17025 accredited calibrations for Series 2300 sources, Series 2600 and Series 2400 SourceMeter® instruments, Integra Series products, Series 2000 DMMs, and the Model 6517A Electrometer. This list of models is expected to be expanded in the near future. Customers can be assured that their instruments are being calibrated to the highest industry standards and will provide consistent, quality measurements. Routine calibrations help avoid down time and prevent costly quality problems.

Helga Alexander, Keithley's Metrology Services Manager, explains how important the new accreditation level is to Keithley customers. "ISO 17025 accreditation proves to our customers that our calibrations are traceable to the international system of units (SI) through NIST (National Institute of Standards and Technology) and are performed with the highest level of technical competence," says Alexander. "Our accredited calibration reports provide information such as measurement uncertainties for each data point, enabling customers to thoroughly assess the condition of their instruments and providing them an even greater measure of confidence," she added.
