Description
xWhy choose AUTOWN for engine diagnostics?
The AUTOWN Professional Compression Tester Kit is built for gasoline engines across cars, trucks, ATVs, and small gas-powered machines. It helps you measure peak compression and compare readings from test to test. Note: this kit is not designed for diesel or crude oil engines, so choose the right tool for your equipment.
Precision you can rely on
The heart of the kit is a 300 PSI triple-scale gauge, designed for quick, easy interpretation in real-world conditions. The three scales—PSI, BAR, and kg/cm²—let you capture readings with clarity, making it easier to spot patterns, track changes over time, and identify when components may be wearing or when tuning decisions are warranted.
What’s included in the 8-piece kit
Each kit comes with a complete set of essentials, all housed in a compact, shock-resistant gray case for transport to the shop or the field.
- Four durable metal adapters (M10, M12, M14, M18)
- Straight and curved rubber cone adapters
- Extension hose for flexible testing configurations
- Quick-release safety valve for safe, one-handed depressurization
- Compact, portable gray case to keep components organized
How it helps you in practice
- Supports quick, reliable checks across multiple engine configurations
- Delivers accurate readings across PSI, BAR, and kg/cm² for flexible assessment
- Safe handling with a one-handed depressurization valve after testing
- Portable design makes it easy to bring to a job site or home garage
In real-world use, you can approach compression testing with confidence, comparing results against known baselines and observing how readings respond to cranking and engine warm-up. This can help you spot signs of wear, valve seating issues, or potential anomalies without guaranteeing any outcome. Treat the data as a useful signal in your diagnostic workflow, alongside visual inspection and other checks.
Portable, safe and ready for the road
The included gray case keeps everything protected and neatly organized, so you can grab the kit and go—from a busy shop bench to a roadside diagnostic call. The combination of robust adapters, flexible hoses, and a precise gauge ensures you have a practical tool that fits into everyday maintenance and inspection routines.
