Understanding of Calibration

Policy :

KTS is committed to deliver total customer satisfaction complying ISO/IEC 17025:2005 with continually improving the effectiveness of the management system also by developing good professional practices & providing required resources and maintaining accuracy, precision & reliability based on national / international standards to our laboratory personnel.
And For that we are here try to understand you :

What is Calibration ?

Calibration is an activity of Checking or Correcting, Unit Under Calibration by comparing with Standard and taking the result within acceptable tolerance.

Example :

It is clear that a car has to be regularly maintained and brought in for roadworthiness test at least once a year. It is the law. We are also aware that this ensures our safety and that the car will serve us throughout its lifecycle.
It is, clear to everyone that a measuring instrument, too, needs maintenance, servicing, technical examination, etc., even if it is not broken.
As is the case with the usual wear and tear of the car's brakes, spark plugs and other parts, components of measuring instruments also age. With time and use, especially incorrect use or misuse, the capabilities of instruments deteriorate.

Why Calibration Required ?

Correctly performed calibration increases productivity, optimizes resources, and assures consistency, comparability and compatibility of products and services, as well as their acceptability anywhere in the world.

What is Uncertainty of Measurement ?

Uncertainty of measurement is the doubt that exists about the result of any measurement.
In another way, In metrology, measurement uncertainty is a non-negative parameter characterizing the dispersion of the values attributed to a measured quantity.
Note : Better Uncertainty of your instruments’ make more less doubt in your mind.
