For measuring the compression pressure on the spark plug hole. With this compression meter for petrol engines you can quickly assess whether you have a loss of compression. This way you can detect problems, such as worn piston rings, burned valves, worn valve guides or a leaking head gasket.
This set is very complete and suitable for both small and large shaft connections. The manometer (range: 300 Psi / 20 Bar) is easy to read and has a vent valve on the side to release pressure after the measurement. A flexible hose is available for areas that are difficult to reach. Screw the end of the hose into the spark plug hole. When the hose is in place, you can easily click the meter into place via the quick coupling. When you have finished measuring, simply click the hose loose again.
If you have easy-to-reach shafts, use the included fixed rod. This works firmly and quickly, because you do not have to screw. There is a rubber conical connection that closes the shaft.

Test compression and leakage on both diesel and petrol vehicles.Test a wide range of modern engines including HDI,TDCI, pumpe duse & older diesel and petrol engines.

Accurately measures cylinder compresion levels.
