Spectrum Metrology is pleased to introduce a ground-breaking handheld gauging system to the MRO Europe exhibition for rapid micro-defect/corrosion analysis directly on the shopfloor. The 4D INSPEC Â® inspection gauge is a completely new method of reliably measuring micro-defects in 3D such as scratches nicks, pits, protrusions, radius of curvature of grooves, spheres and shafts â€“ even rivet geometry.

How often should I have my metrology instruments calibrated?
We are often asked how frequently metrology instruments need to calibrated - here are a few guidelines to help you decide ...
Only the end-user can decide the frequency, but your decision should be based on some or all of the following criteria :
1. Does the item have mechanical movements or is it a reference standard ?
Instrument systems (Talyvels, Autocollimators, Telescopes, clinometers, etc) having adjustment knobs and focusing mechanisms etc, may require service/repair/re-calibration more often than a reference standard
2. Whether it is a 'master' or 'working' item
If the item is used on a daily basis, the likelihood of misuse is more prone than if it is a reference standard that may only be used on a monthly or quarterly basis .
3. The frequently with which it is used
The greater the use, the greater the likelihood of damage or wear occurring.
4. The environment in which it is used
An item that is used in volatile, dusty, or workshop environments may demand a shorter re-calibration frequency than that of an item that is used in a laboratory or standards room.
5. The experience of, and care taken by staff using the item, and the classification of the items use
Will it be used by trained personnel only, or is it a ‘common access’ item?
6. The nature and accuracy of the work undertaken using the item
Higher accuracy measurements with smaller uncertainties can influence the frequency at which the item is re-calibrated .
7. Whether there are ISO or other International audit requirements
Some auditors may impose a new calibration if it is their considered opinion that the original certificate is now ‘out of date.
Generally we find that most users of the Taylor Hobson autocollimators, telescopes and precision levels need to send their instruments for maintenance and calibration every 1-2 years.
Spectrum Metrology is the authorised agent to Taylor Hobson for the service and repair of their electro optical metrology products (autocollimators, alignment telescopes, precision levels and clinometers) and uses the services of the Taylor Hobson UKAS calibration laboratory for traceable certificates of calibration.
