Hydraulic Injector Comparator HA230

The Hydraulic Injector Comparator HA230 is a stand-alone machine designed to test hydraulically actuated electronically controlled injectors.

It features a graduate metering system and comprehensive electronic controls, enabling a full range of tests to be performed on up to 4 injectors at a time. The machine incorporates a single test oil supply, temperature controlled, with fuel and hydraulic pressures controlled individually. An additional injector nozzle spray check station enables the injected fuel spray pattern to be viewed by the operator.
