About Us
For 11 years, Flutree has led smart mobility innovation with advanced diagnostic solutions.
Our intelligent tools empower technicians and owners worldwide to accurately identify electrical faults, optimize performance, and raise standards in repair precision and process efficiency.
We continuously advance technology to make professional diagnostics on-call, resolving breakdowns without the financial strain.
Repair Experts in Your Palm
Circuit Knowledge at Hand
Professional Car Repair
For Truck, Tractor & Trailer
How did we get our start?
Born from real-world repair challenges. We saw a need for better tools and built one with technicians.
What makes our products unique?
We pack professional automotive electrical testing into one compact, intuitive device. It’s built specifically for the job.
Why do we love what we do?
We see the impact firsthand — when a technician saves hours of guesswork, or when a clear reading prevents a costly misdiagnosis. We don't just make tools; we make trust, precision, and confidence tangible.
Reliable Product Support
All-in-One Automotive Electrical Diagnostic Expert
Integrates Relay Testing, Circuit Tracing, Breaker Finding, Battery Analysis, Component Activation
Smart Trace & Locate
When used together with the matching P181, the P350 circuit tracer enables intelligent pathfinding and breakpoint location functions.
Battery Diagnostics
The P350 automotive circuit tester is equipped with a new generation of upgraded chips, resulting in higher measurement accuracy.
Component Activation
In DC voltage mode, components can be directly activated by connecting the P350 power probe tip to an auxiliary ground wire.
Overload Protection
The P350 electric tester tool features a flexible probe and overload protection, making your testing more convenient and safer.
Auto Shop & Automotive Professional Wiring Tester
Complex car sensors and harnesses slow down repair work. Simplify daily electrical checks, speed up whole-vehicle diagnosis, and greatly improve workshop work efficiency.
Excavator & Construction Equipment Wiring Probe
Long-haul vehicles face hidden wiring defects. Support fast roadside inspection, effectively prevent sudden breakdowns, and cut high towing and maintenance costs.
Trailer Light & Farm Trailer Light Inspector
Broken trailer lights cause serious road safety risks. Test tail light terminals and harnesses on site, fix lighting issues instantly, and meet road legal driving requirements.
Tractor & Farm Equipment Circuit Analyzer
Aging wiring brings frequent power failures on farms. Adapt to dusty outdoor environments, test connectors fast, and avoid unnecessary delays in daily farming work.
Excavator & Construction Equipment Wiring Probe
Harsh job site conditions easily wear machine wires. Accurately find short circuits and poor connections, reduce unexpected downtime, and keep construction equipment working steadily.
Marine Boat & Yacht Electrical Troubleshooter
Moisture and corrosion often damage marine wiring. Quickly check on-board connectors and circuits, locate hidden faults in time, and ensure reliable electrical performance for all watercraft.
COMPATIBILITY
Why do I need this P350 if I already have a multimeter?
While multimeter measure basic voltage/resistance, P350 is specialized for automotive diagnostics. It offers smart wire tracing, battery load testing, component activation, built-in overload protection and 20+20ft cables—features multimeters lack.
What if the probe isn't sharp enough?
Our high-hardness steel probes are factory-sharpened. If dull, gently sharpen the tip with fine sandpaper or an oil stone while maintaining the original angle, then clean with alcohol. Severely damaged probes can be replaced via official channels.
Is the device waterproof?
The Flutree P350 has an IP30 rating, resisting light splashes but not submersion. Avoid prolonged use in rain/humidity. Ensure it's dry before use after exposure to water, and disconnect power immediately if it gets wet.
How do I replace a broken probe?
The Flutree P350 probe is removable and easy to replace: unscrew the fixing nut at the device head, remove the old probe, insert a new one, then tighten the nut. Replacement probes are available via official channels.
What vehicle voltage systems are supported?
The Flutree P350 supports 9–30V DC systems, including 12V cars/SUVs and 24V trucks/buses/construction machinery. It works with most passenger vehicles, commercial trucks, agricultural equipment, and marine vessels.
