Recalibration through VWRCATALYST Program is Easy

Accredited Recalibration Services for Thermometers & Hydrometers

Individual calibration of an instrument utilizes prescribed test procedures and methods, as defined by NIST. 4 Performance of your instrument is compared

to certified standards at specific test points4 Specifies corrections to one-tenth of the

smallest division4 Provides a signed report of results and

test conditions

4 Your instrument will be inspected under magnification for any defects, cracks or other impurities that may impair the functionality of the instrument

• Calibrations for temperature points between 0°-100°C (32°-212°F) for thermometers and 1or 2&3 calibration points for hydrometers.

• Meets the quality and record keeping requirements for ISO/IEC 17025:2005, ISO 9000 and ANSI/NCSL Z-540

• Can assure conformance to internal SOP, quality control or other regulations

• Can be used as a reference standard for calibration of other instruments

FAQ’s:What is the difference between a Statement of Accuracy/Traceability and a Calibration Report?

Statements of Accuracy/Traceability are your assurance that an instrument has been manufactured by comparison to NIST traceable instruments, with known uncertainty and an unbroken chain to the metrology standard. The standard accuracy is good for the life of the in-strument. This is not considered “calibra-tion” according to the definition recently adopted by our accrediting body and other regulatory and standards govern-ing bodies.

A calibration at specific points (any on the scale) is an additional process. Individual applications, processes, standard con-formances, and reporting requirements may dictate the need for calibration that meets international standards. This would be user specific, and you would need to review the standards to which you con-firm. Our calibrations and the Reports we issue conform to ISO 17025:2005 and ANSI/NCSL Z-540, and meet the require-ments of most regulatory agencies.

VWR offers instruments that have State-ments of Traceability/Accuracy as well as precalibrated instruments that come with a Calibration Report. VWR can assist you with choosing the instrument that meets your needs and the calibration service you may require.

How often do I need to recalibrate an instrument?

In general laboratory use, we recommend calibration of electronic or liquid in glass thermometers at one year intervals. NIST further recommends six month intervals for thermometers used as standards. Other factors to consider in determining calibration intervals include:• Accuracy requirements set by

customers• Requirements set by contract or

regulation• Inherent stability of the specific

instrument or device• Environmental factors that many af-

fect the stability

In the absence of other external require-ments for specific intervals, internal mea-surement assurance programs that in-clude cross-comparisons of primary and secondary measurement standards,

provide validation of data upon which intervals may be based. NIST Publica-tion GMP-11, Good Measurement Prac-tice for Assignment and Adjustment of Calibration Intervals for Laboratory Stan-dards, establishes calibration intervals for standards and instrumentation used in the measurement processes. NIST guid-ance documents are available on their website.

What type of accreditations does your laboratory have?

Our laboratory is accredited to the ISO 17025:2005 standard by the American Association of laboratory Accreditation which also includes the requirements of ANSI/NCSL Z-540, certificate number 2448.01. Out Quality Management Sys-tem is registered ISO 9001:208 and our Environmental Management System is registered ISO 14001:2004
