Accurate measurements play a vital role at each stage in development and production of quality product. The effectiveness of quality control steps depends directly on the accuracy and confidence with which the Test & Measuring instruments (TMI) can yield test results. Thus systematic and periodic checking of Test & Measuring Instruments is very essential for reliable measurements. The process of periodic checking of TMI by comparison with another instrument of better accuracy is termed as Calibration. Periodic calibration of TMI provides the most vital link between international standards of measurement and the day-to-day test & measurement data through the medium of National measurement standards held by the National standards laboratory. The laboratories complying with the requirement of ISO/IEC 17025 standard are competent to produce reliable and valid results. Accreditation of laboratory ensures compliance to ISO/IEC 17025 standard and competence of laboratories. We are involved in providing services for the following departments at our state of the art laboratory which is equipped with reference calibration standards from Fluke, Yokogawa, and Eurotherm which are traceable to National and International standards like NPL, ETDC, ERTL, FCRI, and CPRI.
