About HPCL Calibration Laboratory

HPCL or Hindustan Petroleum Calibration Laboratory is the major provider of energy in India. It was initially incorporated as a subsidiary company of the Indian Companies Act 1913. They perform a wide range of thermal and mechanical calibration tests. The thermal calibrations offered at Hindustan Petroleum Calibration laboratory include calibrating the range or frequency of the temperature of the liquid-in-glass thermometers, RTDs with the indicator, and digital thermometer. The types of mechanical calibrations offered are determining the range or frequency of the density of the instruments like density hydrometers, specific gravity hydrometers, alcoholometers, and kinematic viscosity of glass capillary viscometers and Newtonian liquids. Their calibration laboratory is equipped with all the modern machinery and top-quality instruments, thus ensuring that the results provided by them are correct. The Hindustan petroleum calibration laboratory is an ISO/IEC 17025:2005 accredited laboratory.
