2 Stagemaster HH720

2 Stagemaster HH720

The 2 stagemaster HH720 is a cost effective easy to use module for testing two stage injectors. The HH720 is used in conjunction with either the Testmaster 2 HH700 or Testmaster 3 HH701 injector testers.
The 2 Stagemaster HH720 features an LCD display and simple automatic controls to determine the second stage opening pressure (NOP2). The first opening pressure (NOP1), spray pattern, back leakage, front leakage are checked using the Testmaster 2 HH700 or Testmaster 3 HH701.

Benefits

• Efficient method of establishing Nozzle Opening Pressure (NOP2) without having to remove the injector from the host Testmaster and with no time consuming test bench set up.
• Quick and easy to use.
• Enables the flow and second stage opening pressure of all two stage injectors to be verified without having to dismantle the injector or isolate the first stage lift.
• Creates opportunities for servicing two stage injectors in diesel workshops.
• Can be used as a comparator when injector test data is not available.
