Objective of Pressure Laboratory

The main objectives of the pressure laboratory are to establish, maintain and upgrade national primary standards of pressure measurements compatible to international standards through research and development.

The aim of the pressure laboratory is to realize, maintain and disseminate the derived SI Units of pressure(Pa).The laboratory has been providing apex level calibrations in different pressure regions and maintains traceability of pressure measurements at international level.

The main activities of the laboratory are participate inter comparisons in the field of pressure and to assure international traceability, provide calibration service to calibration laboratories, testing laboratories and to industry.

Pressure is a derived Unit combining the SI Units of Mass, Length and Time.

SI Unit - Pa=Nm-2

Standards

1. Hydraulic Pressure Standards

The hydraulic pressure standard in the range up to 200 Mpa
