MS909 vs MS919 vs Ultra: Specs

MS909 vs MS919 vs Ultra: Compare

Size & Display

MaxiSys Ultra (12.9″ 2732 x 2048 DPI) comes with a larger screen and higher resolution than MS909 and MS919 (both 9.7″ 1536 X 2048 DPI). What’s refreshing, Ultra features a split-screen navigation that allows you to run multiple applications simultaneously, a superb skill maximizing your work efficiency.

Battery & Memory

Both MS909 and MS919 utilize 128GB SSD / 4GB RAM, while Ultra uses a bigger 256GB SSD / 4GB RAM memory storage. All scanners can run 8 hours without break, but Ultra stands out with a stronger 18,000 mAh battery compared with the other two (15,000 mAh). Moreover, the convenient docking station in Ultra ensures you always have the power during operation.


The top reason separating MS919 and Ultra from MS909 is the advanced 5-IN-1 VCMI,a small but complete reliable lower computer with powerful hardware extensions, such as oscilloscope, waveform generator, multimeter, and CAN BUS tester.

Repair Assist

While all three devices are equipped with repair assist service, MS 909 has to give way to its counterparts in function coverage. Thanks to the versatile VCMI, MS919 and Ultra show code-related problems with component tests and direct you to the Oscilloscope with a single click. They also provide easier and faster operation by built-In preset guided tests, which enable you to customize probe specification and check waveform libraries. As mentioned before, component tests, along with saved test configurations and data graphs are all available at hand.
