Calibration Services

Calibration is an elementary process in which an instrument is adjusted to the required accuracy and precision to eradicate or minimize the unfairness in the readings of an instrument. Any instrumentation design demands elimination of elements that creates inaccuracy in the measurements despite of different testing schemes for every product. Calibration is recommended for various purposes like carrying out test through a new instrument, testing an instrument after it is repaired etc

Detailed Description for Calibration Services

 Calibration! What is it? 

A set of operations, performed in accordance with a definite procedure that compares the measurements performed by an instrument to those made by a more accurate instrument or a standard for the purpose of detecting and reporting, or by adjustment, errors met in the instrument tested. 

Purpose of Calibration

To ensure readings from an instrument are consistent with other instruments and to determine the accuracy of the instrument i.e. that it can be trusted for its observed/displayed measured value.

The value of calibration for industry 

·         To ensure that products are manufactured to specifications.

·         To demonstrate that the industry operates a quality system and technically competent and are able to generate technically valid results.

·         To increase quality & value of product.

·         The calibrated measuring instruments (working standards) have the assurance of an unbroken chain of national/international measuring standards.

 What is Traceability? 

Property of the result of a measurement or related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties.

Why measurements must be Traceable? 

  • Traceable measurements ensure the uniformity of manufactured goods and industrial processes.
  • To support equity in trade as well as compliance to regulatory laws & standards.
  • Essential to the development of technology.

Calibration Measurement! How ? 


  • Verifying the performance of the test instrument which involves applying a standard value to the instrument and observing how it behaves.
  • Adjust the response of the instrument, wherever possible (After verifying response, reset, adjust/correct the instrument via internal control which in normal course is not accessible).
  • Obtain correction factor for the test instrument.(Accordingly correction factors/calibration constants are calculated & incorporated in measurements).
