Review on ALLOSUN EM276 Fuel Injector Tester by John Bourgeois

For the money you are paying this is a fantastic diagnostic tool for your toolbox. I'm a certified master technician and this is an essential tool for some of the tests I have to do on a weekly basis. Quality: Not as good as your branded snap-on, Mac, or OTC tools, but the functionality is there. . You can tell it feels like cheap plastic. but the price is right. Function: Exactly as described. I checked the pulse width modulation output with an oscilloscope. It matches the display and is reliable for testing. Pros: great price. carry case and instructions. the mode you are in. In general: I recommend.
