Designed to determine the tightness of combustion chambers in engines. The instrument uses the method of determining the pressure drop of compressed air when it is supplied through the spark plug hole. It is equipped with two pressure gauges displaying the value of compressed air pressure in the line and inside the combustion chamber to ensure the accuracy of the measurement results. The measuring range of the set instruments is 0 to 100 psi (0-700 KPa), with a division value of 2 psi (20 KPa). The pressure gauge displaying the pressure in the combustion chamber has three color-coded measurement zones. The set is completed with a high pressure hose and adapters for M14 and M18 plug holes.
