Compare Cylinder Compression Across Six Stored Tests
The PT610 shows live and average compression with cylinder temperature and measuring time, and saves six data sets so you can compare cylinders. Pick the adapter that matches the spark-plug opening.
- 6 Stored Data Sets
- 0–29.4 Bar Range
- 2.8-Inch Backlit Display
- 78.7-Inch Reinforced Hose
- 5 Thread Adapters
Key Features

Good to Know
Care
- Compare cylinders under the same conditions and follow the engine’s compression-test procedure.
- Display resolution is not measurement accuracy; recheck a low cylinder with the specified follow-up test.
