Specifications: Material: Copper Dual Gauge Readings: 0-300psi, 0-20bar (1bar=100kPa) Test Unit/Mode: bar, psi Pressure Gauge Diameter: 3in/75mm Pressure Gauge Height: 5.04in/128mm Adapters Thread Size: M10 * 1.0mm, M12 * 1.25mm, M14 * 1.25mm, M18 * 1.5mm Hose Overall Length: 17.72in / 450mm Straight Line Pressure Tube Length: 5.9in / 150mm Angled Pressure Tube Length: 6.30in / 160mm Package Size: 29.5 * 21 * 5.5cm / 11.61 * 8.27 * 2.16in Package Weight: Approx. 1020g / 36.0oz Use Methods: 1. Start the engine and run to the normal working temperature. After the engine stops running, unload all spark plugs; Make the throttle fully opened and press the connection of the pressure gauge on the spark cold hole; 2. Motors drive the engine to rotate at 100-150R/MIN speeds for 3-5 seconds. At this point, the pointer on the instrument will gradually rise, but will stop at a certain value. At this time, the indicator value is the compression pressure of the cylinder; Press the button to zero the pointer;you can test 2 to 3 times to improve the measurement accuracy; 3 cylinder pressure more than 0.9 MPA, and 4 < 8%. If the measured value is less than the prescribed value, and the intake system is normal, it can be explained that there is leakage between the cylinder and piston, cylinder head. It may be that the original cylinder, piston, valve, piston ring appear abrasion, ablation and other bad conditions. If the measured value is greater than the prescribed value and the intake and exhaust system is normal, the possible reason is the serious volume of combustion chamberage List:1 * Gasoline Compression Tester+1 * Hose+4 * Thread Adapters （M10, M12,M14,M18）+1 * Straight Line Pressure Pipe+1 * Angled Pressure Pipe+1 * Storage Case
