Understanding Calibration Services

By Carey Bourdier


Proper calibration has an enormous effect so many aspects of our daily lives and you probably aren't even aware of its importance. In order for every piece of machinery used in all types of production to run to exact specifications, they must be calibrated. The result of improper calibration could be a dysfunctional product. When calibration is not precise, the end result can be a catastrophic failure of machines, optical instruments, tools and more.

Calibration is, in simple terms, a comparison of two different measurements. For instance, perhaps you have an item such as theodolite, which is an optical instrument used by surveyors to measure angles in both the horizontal plane and the vertical plane. This theodolite must be calibrated in order to ensure that the angles are being measured accurately. To calibrate this theodolite, it will be tested by using another device that also has been calibrated to standard measurements.

The theodolite is just one example and any machine you can think about needs calibration. For instance, imagine what a book, magazine or newspaper would look like, if the printing press was not calibrated. Imagine what would happen if a device such as an X-ray machine was not calibrated correctly. Even your truck, van or car needs calibration to keep the engine running properly. Your speedometer, for instance, is calibrated so that the speed is displayed correctly. Even just being off by a couple of miles per hour can cause you to end up with a speeding ticket.

Calibration services are needed regularly and for many objects, it is required that certification accompany the calibration to ensure that the machine has been tested and calibrated properly. This certification might be needed for a new machine or perhaps an older machine to ensure that it still is working correctly.

Often, if a device has been repaired or altered, then calibration services are needed. In addition, some items require certification and calibration services after a specific period of use. For instance, maybe your piece of machinery requires calibration services every year or perhaps every other year. In these cases, you will want to contact an expert in calibration services for your specific instrument or machine.

In general, companies will need to hire someone, such as the staff of Warren Knight, to provide these calibration services. Warren Knight offers calibration and certification services for hundreds of different instruments, machines and devices and also provides repairs for these items. In addition, they have many helpful items that you can rent if needed, rather than purchasing an expensive item. This includes everything from total stations to clinometers to levels and a huge variety of optical instruments and angle measuring devices.
