PRO DIFFERENTIAL PRESSURE TESTER KIT WITH EXTENSION TOOL
Quality product that works very well. The hard case keeps everything safe and together between uses. I hope my Wife appreciates the new air compressor shes getting for her birthday!
Nice piece of equipment
Certainly a better compression tester than others I have used in our shop in the past
So easy to use. The included storage box is handy too.
Worked great. Reliable and repeatable readings. The case is a nice addition to store and carry the unit. The extension also made the job easier. I learned that if you set the cylinder at exactly TDC, the compressions reading can be done by one person. If not, another person is needed to hold the prop from turning backwards due to the pressure. This could have been explained by the directions...
Quality tester, nice to have the Master Orifice Valve to check the accuracy of the gauge. I vae seen many testers where the actual gauge is reading way off. This one so far is accurate as hell.
Super pleased with this purchase and I havent even used it yet. Could not beat the price and I need not comment on the super service I have always gotten from Spruce. The quality of the tester (I did fire it up with my compressor) is excellent and the inclusion of the Extension Tool was just icing on the cake and will be a great help during Annual. The case holds the tool and has a captive slot for the extension as well as an extra spot for a different sized plug adapter.
The kit arrived on time and in good condition. It is nice to have both the standard plug fitting for tight spaces and the extension tool for longer reach. The hard case is durable and has snap-in recesses for the various parts to hold securely. The instructions were clear and succinct. The tester worked as intended and was easy to use. Would definitely recommend to others.
This compression tester does the job just fine. The extension helps on some engines where baffling and wiring makes the plug hole difficult to get your fingers to to install the normal plug adaptor.

They calibration is due 1 year after purchase unless the unit is dropped or grabbed by the gauges which could throw off the calibration of them.
