Question:medium
Which is the most suitable instrument to calibrate the pressure gauges?
Which is the most suitable instrument to calibrate the pressure gauges?
Show Hint
A Dead Weight Tester is a primary standard because it relies directly on fundamental physical quantities (mass, length, time) to define pressure.
This makes it highly reliable for industrial gauge calibration.
