Mass & Volume
CALIBRATION FACILITY
MSIR INDIA’s Mass & Volume Metrology Laboratory provides ultra-precision calibration for OIML Class E1, E2, and F1 weights, microbalances, and pharmaceutical volumetric equipment. Operating inside a positive-pressure, low-air-velocity cleanroom with automated robotic mass comparators and air-buoyancy CIPM formula corrections, we achieve sub-microgram repeatability.
