Compatibility depends on injector specifications, voltage requirements, and adapter size.
- Only applicable to gasoline injectors; completely incompatible with diesel engine injectors
- Power adapter, fuel pressure tester and injector cleaning liquid are not included in the standard package and need separate purchase
- The main unit power plug adopts US standard socket; users in other countries need to prepare conversion adapters
- It only outputs driving pulse signals, and cannot independently provide fuel pressure for spray observation
- Not suitable for high-voltage piezo injectors outside the 5V/12V drive voltage range
- For indoor bench use only; avoid splash water, corrosive liquid and heavy dust working environment
- Cannot test heavy-duty diesel truck injectors, construction machinery fuel nozzles
- Pure bench hardware tester, no built-in activation chip, annual subscription or paid authorization required, plug and play after connecting power
- Mandatory separately purchased matching supplies: 12V DC power adapter (≥1.5A), fuel pressure tester, injector cleaning agent
- All standard test accessories (clamps, adapters, rubber rings, sealing tape, storage bag, manual) are included in the package without extra purchase
- No software license binding, all test modes are unlocked permanently out of the box
- Standalone handheld hardware without built-upgradable firmware, independent APP or PC control program
- All mode switching, voltage adjustment and test start/stop operations are completed through physical buttons on the front panel
- No computer connection required during the whole test process, no Windows/Mac system compatibility restrictions
- No user-upgradable firmware inside the machine; pulse logic and protection programs are solidified at the factory
