Feature●Widely Used：100% brand new and high quality gasoline compression tster suitable for professional use on petrol engines of cars, motorcycles, motorbikes, trucks, and other petrol vehicles.●Dual Scale Tester：Dual scale pressure testing gauge reading range: 0-300psi/0-20bar. It is easy to reading and use.he kit comes with straight and angled push-on connectors as well as a storage case for easy carrying.●Premuim Adapters：This compression tester kit includes 4 size of thread adapters for different spark plug holes. Spark plug adapters have O-ring for improved sealing. Brass fittings are very durable in use for a long time.●Function：This compression tester sets up quickly to give you accu e readings for finding faults in valves, piston rings, cylinder bores, or head gaskets, reminding you to inspect your car or vehicle condition regularly and promptly. Helps you do the job for a reasonable price.●How to Judge：Generally, the car cylinder pressure is more than 0.9 MPA, and 4 < 8%. If measured value is less than prescribed value, and the intake system is normal, it can be explained that there is leakage between cylinder and piston, cylinder head. It may be that the original cylinder, piston, valve, piston ring appear abrasion, ablation. If the measured value is greater than prescribed value,intake and system is normal, the possible reason is serious volume of combustion chamber.●Dual Scale Tester：Dual scale pressure testing gauge reading range: 0-300psi/0-20bar.

Usage:
1. Start the engine and run to the normal working tempe ure. After the engine stops running, unload all spark plugs;
2. Make the throttle fully opened and press the connection of the pressure gauge on the spark cold hole;
3. 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;
4. Press the button to zero the pointer;
5. According to the above steps, the measurement is repeated 2 to 3 times to improve the measurement accuracy;
