Pressure & Vacuum
CALIBRATION FACILITY
The MSIR INDIA Pressure Metrology Laboratory specializes in pneumatic and hydraulic pressure calibration across 7 orders of magnitude. Using automated deadweight testers with tungsten carbide piston-cylinder units, localized gravity compensation (g = 9.7828 m/s²), and high-stability quartz transducers, we serve aerospace, oil & gas, process industries, and defense standards.
