AZUNO Cylinder Compression Tester Kit, 200 PSI Digital Compression Gauge with Adapter & Hose, 8 Pieces Professional Compression Test Tool for Gasline Engine and Small Engine

Está más o menos

Seems versatile but would not read correctly. Had to use my older analog gauge.

Used this once on my Jeep and it worked as it should.

Right out of the case this tester does not work. The diagram show that it has 2 air valves in the hose and gauge, but this kit has none. it reads 0.0 PSI I do not recommend this kit for anything.Does not read accurate PSI and will not hold pressure when testing compression. jumps from 0.00psi to random PSI and never the same readings. Very poor quality product never buy again. This was the second tester from this brand and it is junk.

Cheap made but worked

As advertised

This worked for me one time. It seems to me the check valve inside it does not work. The gauge will get readings and then the pressure bleeds off so when you think youre done, it shows a lower pressure than you actually got. It's junk.

Completely inaccurate even compared to the harbor freight gauge. Thought this would be a great cheap field tool for my business, after all it’s just a gauge and a hose. Gave readings of 60 lbs when in fact the value was actually 110 lbs checked with a snap on gauge as well as a cheapie from the auto parts store. If you’re thinking of buying this, make sure you have another gauge to verify you values.
