The nozzle tester is used for inspection and adjustment through the measurement of injection open valve pressure, oil-tightness test and visual inspection of injection angle and atomized state of an injection nozzle for a diesel engine.
Model DI-50B is provided with a valve on Model DI-50.
The valve is closed to cut pressure transmission to the meter so as to protect the meter when the injection state is visually checked or the injection nozzle is removed.
