Accredited Calibration Services

 The Industrial Metrology Laboratory has established the facilities to provide accredited calibration services as per ISO/IEC 17025 in Mass, Temperature, Dimension, Electrical, Pressure and Volumetric Areas.

Calibration services are provided to local industrialists, BOI companies, government organizations, medical and other testing laboratories on their request to maintain their quality systems as per the international standards and obtain certifications.


The mass laboratory is equipped with higher precision comparator balances and set of class E1 weights traceable to international kilogram. The calibration measurement capability (CMC) of the laboratory provides a higher level of accuracy for the customers and undertakes the accredited calibration services to

  • Analytical/Electronic Top Loading Balances and weighing scales 
  • Weight classes of E2, F1, F2, M1, M2 & M3 and industrial weights from 1mg to 20kg


Temperature measurements are very cruisal in Apparel and construction industries and medical sectors. The following accredited calibration services which are traceable to international standards are offered.

  • Liquid-in-glass thermometer
  • Dial thermometer
  • Platinum Resistance Thermometer (PRT)
  • Digital thermometer
  • Thermocouple
  • Temperature indicator and controller

Performance tests on

  • Block calibrator
  • Oven/Incubator
  • Stirred Liquid Bath
  • Autoclave
  • Muffle Furnace


Dimension measurements are critical for several BOI companies, ship building industry, construction companies and manufacturing sector. Grade K gauge block set traceable to international standards is used for Calibration. We undertake the following accredited calibration services in length measuring equipment. 

  • Gauge blocks
