Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%), easy to read 3" gauges spend less time to give accurate results. Compression leak tester hooks up to air compressor(provide yourself) can help to detect common engine faults such as worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets.
