Meccion Engine Cylinder Pressure Gauge Diagnostic Tool 8pcs Professional Petrol and Diesel Fuel Pump Compression Tester Set

Haven't had any previous products to compare it to, however I was able to diagnose a problem with my sons car. Easy to use and would appear to be good value for money, a good addition to the toolbox.

Son''s Yamaha Aerox moped (70cc kit) wouldn't start - by elimination lack of compression was suspected - couldn't get the gauge to move at first so tested it with a bike pump and got the needle to move ok. Fitted new piston ring and tried again and the guage went up to 75psi after a few kicks - happy days!

great quality,easy to use.

It's very easy to use and includes multiple sizes so I can use it on my lawnmower aswell as the 2 stroke strimmer.It is reasonably accurate for the price and is well worth having.Overall it's a good product at a cheap price.

Brilliant product, used it without any problem.As spark plug slots are mostly deep and you have to screw the tube blindly by rotating the rubber pipe in the deep slot, which doesn't give you confidence that it has been screwed properly!Not sure whether it has any effect on the cylinder pressure measurment.

Hi thereI wanted to test the compression in my camaro,it has 350 sbc,this kit worked very well on this engine and has many adapters for other thread sizes,good price,i like it

Bought this to carry out a compression test on my gen 7 Celica vvti engine. Nice and sturdily made with good heavy rubber hose and a tough case to protect it in the toolbox. The hose already has a thread which fits standard spark plugs so no adapter required in my case.Screwed in and sealed well and held pressure perfectly with no leaks, very happy with purchase.

Worked great on my Yamaha Vtwin. I assume it’s the same kit being sold elsewhere for more ££.

Good productEasy to SwedenExactly what I need

Cumple su objetivo perfectamente

Non mi aspettavo chissà cosa, mi sono dovuto ricredere, messo in funzione subito dopo il suo arrivo su Mercedes A150, cilindro 4 5bar cilindro 3 4,5bar cilindri 1 e 2 15bar. Per essere sicuro lo testa con altro attrezzo stessa misurazione. Per me ottimo

Überprüfe damit Mofamotoren und habe damit schon einige defekte Zylinderköpfe festgestellt.

The gauge is wrong! Multiply all readings with 0.667
