It is a simple device used to measure the pressure inside tires. Basically it consists of a piston whose movement can be tracked on a scale with the help of a calibrated rod connected to it.When a balance between the two forces acting on the piston is achieved, the value of the pressure in the tire can be read on the calibrated rod which moves simultaneously with the piston.
