We utilize tooling and automation equipment designed and built to the highest industrial standards and certified by our manufacturing operations to ISO 9001.

Calibration Services

Landau Gage provides calibration services for all of the gages we manufacture. We also have the capability to provide accredited or NIST traceable calibration for a broad array of instruments and standards.

FAQ’s

Do you have a pricing list for the equipment that you have the capability to calibrate?

Due to the many variations of these instruments, it is not possible to provide a complete price list. We would advise that you submit a request for calibration with the description of the instrument through Contact Us and our staff would be happy to provide you a detailed price quote.

Can you provide me a recommended calibration interval for my instrument?

We cannot recommend a calibration interval. This would be a conflict of interest for us. You must choose a calibration interval based upon your company’s quality policy and the performance of the instrument over time, but we would be happy to provide you with assistance if needed in helping to determine the interval for your calibration.

What is the difference between a NIST traceable calibration and an Accredited calibration?

An ISO/IEC 17025 accredited calibration is recognized internationally. ISO 17025 accreditation is a statement to the competence of the calibration laboratory.

Accreditation is a process where an Accreditation Body (such as A2LA) reviews and validates all calibration processes of the respective calibration provider. This includes their management processes and mechanical processes on a regular basis.

The Accredited Calibration certificate thus has more credibility as the calibration is performed under certain standards which are verified by accreditation bodies through regular auditing.

A NIST calibration simply means that the equipment being used to calibrate customer’s equipment is traceable to NIST standards. A NIST traceable calibration does not indicate or determine the level of competence of the staff that performs the calibrations, nor does it take into account the monitoring of the environment in which the calibration was performed.

How do I decide between a NIST traceable calibration or an ISO/IEC 17025 Accredited calibration?

The choice is often decided by a company’s quality department. The decision can also be made depending on how the equipment that requires periodic calibration will be used. For example, if the equipment is being used in a critical application an ISO/IEC 17025 calibration may be required. If the device is used more for reference purposes in a low risk setting then a NIST traceable calibration may be all that is needed to fulfill your requirements.

It is ultimately the responsibility of the owner of the device needing calibration to determine the appropriate type of calibration required – NIST or ISO/IEC 17025 accredited – to ensure the calibration meets the needs required in their industry.

What if my instrument cannot be calibrated or does not pass calibration?

If your instrument cannot pass calibration due to an instrument failure, damage or wear you will be notified to determine how you would like to proceed. The decision of whether the instrument is still valid for your processes is entirely the responsibility of the owner of the instrument. However, one of our engineering staff members could advise you on whether the instrument could be repaired or if it needs replacement.

What does the measurement uncertainty stated on my accredited calibration certificate mean? (And why do I need it on my certificate?)

Every measurement is subject to some uncertainty. A measurement result is only complete if it is accompanied by a statement of the uncertainty in the measurement. Measurement uncertainties can come from the measuring instrument, from the item being measured, from the environment, from the operator, and from other sources. Such uncertainties can be estimated using statistical analysis of a set of measurements. There are established rules for how to calculate an overall estimate of uncertainty from these individual pieces of information. When the uncertainty in a measurement is evaluated and stated, the fitness for purpose of the measurement can then be properly assessed as to whether the calibration is adequate to meet the needs of your industry’s requirements.
