The JT200 features transparent cylinders that provide a clear view of the actual spray pattern, helping identify uneven or faulty injection and spot distorted sprays, uneven streams, or poor atomization instantly no more guesswork or swapping parts blindly. As a professional technician said: This is a game-changer. Way easier to find a weak injector than with traditional tools.
  • Precision Flow Measurement Compare Each Injector Side by Side. The JT200 comes with easy-to-read graduated cylinders that let you measure and compare fuel volume against manufacturer specs and across all injectors. Clear injection volume scales and intuitive readings help you quickly identify deviations. No more it looks fine get hard numbers to back your diagnosis and repair decisions with confidence.

Description

Visually compare injector spray patterns and flow rate side-by-side for easy, safe fuel injector testing. Compatible with Φ9–14.5mm injectors, suitable for most 6V&12V gasoline vehicles and motorcycles. 12V power supply, one click to start test quickly, no additional assistance required. Real‑time display rotational speed and pressure values during testing. Automatically simulates a full range of engine speeds -from fast to slow -to replicate real driving conditions. The adjustable test duration (30–600 seconds) enables both quick checks and extended tests for enhanced accuracy and reliability. Manually adjust rotational speed in ±50 RPM every 0.5 seconds, covering a wide range from 100 to 9900 RPM, this enables precise testing at any specific speed for advanced troubleshooting.

FOXWELL JT200 fit for most 6V/12V gasoline vehicles and motorcycles, it comes with three adapter sizes (Φ9-11.3mm, Φ11-12.8mm, and Φ13-14.5mm) Can it clean the injectors? The primary function of JT200 is to inspect spray patterns and flow rate differences. While the pressurized test fluid may flush out some debris during testing, it does not perform a thorough clean and is not a substitute for ultrasonic cleaning. How to select test fluid? It's recommended to use professional test fluid, which is precisely formulated to simulate the viscosity, density, and surface tension of real fuel. This ensures accurate and comparable test results.Never use water, gasoline, or any substitute liquid Can I use cleaning fluid instead of test fluid? Use only test fluid. Substitutes like clean fluid, water, gasoline will damage your tool and injectors.

  • Worth it. Will pay for itself in no time.
Works for what I needed. Simple to use. Seems like it will hold up. I would recommend getting a 110v dc power supply to run it. It does come with battery connectors but a wall plug was more simple. Only thing I noticed was it would run out of fluid before the tank indicated empty. Kinda like the bottom of the hose wasnt held at the bottom of the tank. Overall I am glad I bought it. Used it to test old injectors on a new motor and to test a utv injector. ... show more

  • hit or miss
It worked fine for about 5 minutes, then one of the injector leads stopped responding to the program and went full blast. Could not reset it. Definitely a software glitch. The item itself was of good quality, well packed with good instructions. Will buy again soon and hope for better luck. Price is very reasonable. ... show more

  • Definitely recommend this if you ever have to take out injectors
Definitely takes a little bit longer to go through a V6 or 8 cylinder set of injectors but you are saving a couple hundred verses a set of four injectors tester. I definitely like the clear vile as you are able to see the pattern and the spread and I was able to identify several bad injectors before I put them all back into the motor I was working on. Out of all the testing fluid I definitely recommend getting the blue bottle of fuel from Walmart essentially denatured alcohol ... show more

  • Not User Friendly
This is a hobby grade injector tester. The design is not well thought out. Pressure and pulse width are not adjustable. The injectors have to be removed to empty the graduates. I'm returning mine.

  • Good machine. Pressure is not enough
Machine works well. Nicely packed. 2 cons. 1. You must have a battery. There's no adapter to just plug in or even plug the machine in to the wall. 2. The psi does not exceed 28 psi. Which is not near enough on especially on ls injectors. Those are my only issues I am returning only due to the psi issue and grabbing one I can run proper psi for the test. Other then that machine works great and seems really well made. ... show more
