Test injectors are used at test benches for injection pump tests. They are a very precise calibration device whose design and condition are critical to the correct adjustment of the feed rate of the injection pump performed at the test bench. It is very important to select the correct test injector for the tested type of injection pump. Information about the injector type is recorded in the pump test and adjustment record provided by the manufacturer.
A suitable set of test injectors is an indispensable part of the equipment of every professional workshop that repairs and adjusts injection devices.
