The set for checking the tightness of cylinders is designed to determine the tightness of the engine combustion chamber.
The device uses a method to determine the amount of pressure drop of compressed air when it is supplied through the spark plug hole.
Equipped with two pressure gauges to display the pressure value of the compressed air in the line and inside the combustion chamber, to ensure the accuracy of the measurement results.
Measuring range of instruments of the set is from 0 to 100 psi (0-700 kPa), division value is 2 psi (20 kPa).
There are three measurement zones in the pressure gauge displaying the pressure in the combustion chamber, indicated by color.
Kit comes with high pressure hose and adapters for M14 and M18 spark plug holes
