This compression tester measures cylinder pressure from 0 to 200 psi and 0 to 14 bar on small engines, cars, and light trucks with accessible spark plug holes. It utilizes a 1-1/2" (38.1 mm) dual-scale gauge and includes M14 and M18 thread connections to fit standard engine ports. The compact assembly is sized to fit in a shirt or pants pocket and uses a valve core at the base of the hydraulic hose to maintain reading accuracy.
