Constructed with a 14 mm long reach adapter, this compression tester measures cylinder pressure from 0 to 300 psi. The gauge provides readings in 0 to 2100 kPa, 0 to 21 kg/cm², and 0 to 21 BARs to support various measurement standards during engine diagnostics. It also includes a spare 1251-2 valve core to maintain the compression tester during routine use.
