Many of natural gas fueled cars like CNG cars are subjected tohigher compression pressure compared with gasoline cars.This compression tester allows the measurement of highercompression pressure for these vehicles.To enhance the heat resistance required for the measurement ofhigher compression pressure, heat dissipation performance isimproved by the use of heat-dissipating materials and shape on theend part.
Measurement can be made by a single person since this tester canbe secured by screwing the hose adapter into the spark plug hole.This tester can be used for various types of plugs by fitting any of thethree types (10mm, 12mm, 14mm) of the provided plug adapters.
