Calibration Cell coordinates the calibration and traceability requirements of the campus. The cell carries out these activities using its in house capabilities and where ever required, coordinates with the external agencies to meet the requirements. Reference materials are maintained by the cell for ensuring traceability of measurement to national / international standards.
Mechanical and thermal calibrations carried out by Calibration Cell are accredited by NABL, India. Mechanical calibration involves volumetric glassware, micropipettes, electronic balances, mass sets and rotational speed. Calibration of Relative Humidity (RH) monitors, thermometers and temperature chambers such as incubators are included in the thermal category.
