Compression testers

  • Each individual cylinder or combustion chamber in petrol (gasoline) and diesel engines can be diagnosed by measuring the compression pressure. 
  • The measurement is made via the spark plug, glow plug or injector bore in conjunction with specific adapters.
  • If the measurement values are low or deviate too much, the following may be faulty: piston rings, valves, cylinder head gasket. 
  • The fault location can be further pinpointed by a subsequent engine pressure loss measurement. 
  • Note: Additional adapters for use of the test devices in different engines can be found in our extensive assortment of adapters, see: "Adapter list for compression pressure loss testing units (ZKD).
