Car accidents may happen at any time. Sometimes, it’s because of the external problems like the wheel, the door, or even the brake. But they all can be spotted. What about the ones that are not visible at first glance?
Things like damaged fuel injectors or even malfunctioning sensors can lead to dangerous accidents while driving on a highway or at a higher speed. Such minute problems can cause the car engine to not work properly. But, how can one know about it before riding? Simple… with the help of small engine compression testers!
The best compression testers are a specific type of measuring device used for automotive parts. Specifically, they are used to check the car’s engine heath. The sensors inside can easily detect the problem that helps in diagnosing.
A simple test with this device can indicate where it has gone wrong and how dangerous the fault could be. So, having a car compressor tester and testing the car at least once a month is an important objective before driving off.

Any healthy car engine must have a compression of over 100 psi per cylinder. If there’s not more than 10 percent of the variation, the engine should be working fine. But if it is higher, it’s a critical time to diagnose the problem and sort it out. The small engine compression tester is specifically designed to pick out the pressure readings. Once the hose is attached to the compression gauge, it starts out reading with steady acceleration. If there is a big deflection on the maximum and minimum reading, the car needs to be immediately checked.

Most of the electronic measuring tools require calibration, but not all the time. Specifically when we are talking about the INNOVA 3612 or the OTC 5605! They are calibrated and are manufactured to be precise. So you can always rely on the deluxe compression and get perfect readings with these products.
Well, I’ll be honest about this, I had one 115hp outboard previously and I had tested it. But it’s not with the same adapters. I had to buy one from the local market and luckily it was compatible with the tester. So yes, if you get the right set of adapters, you can easily check on a mercury 115hp outboard.
If you want to check the exhaust backpressure, it’s simple-you need a bigger hose and a better adaptor. I don’t think that most of these products come with such a bigger hose. You can try to find it out in the market, but performing an exhaust back pressure test may be difficult. Most of them are designed to fit into a spark plug hole.
I don’t think that the compression hose is flexible. So directly fitting it onto the air hose will not be an easy solution. For this, you need to have an adapter. If you have the right set of adapters, getting the correct readings will not be a problem. But the manufacturer will provide only one adapter. So you need to be specific about the model you are choosing.
Oh, I wish that it could but unfortunately… no it all depends on the hose which you are using. If you have a diesel compression hose, it should work. However, asking for a reading of the 600psi range will be too much from the compression tester. Most of them come with a maximum reading option of 300 psi. They are designed to work best at their limit.
Having the best compression tester will solve multiple internal problems with your engine. So you need to be specific about the product that you choose. Simply purchasing a random tool may not be a great example of an automotive expert. Of course, you may compensate for the budget, but it must have similar features to prepare accurate reading. Below, I have compared three products which I have picked according to my convenience and you can have a look at them. Do let us know in the comments below about which model matched your preference.

The INNOVA 3612 Compression Tester is my top pick amongst all the products featured. This device comes with a specified adaptor that can quickly identify the damaged pistons and the worn rings. It includes a wide dial face with a bourdon tube meter. Since it is dual-calibrated, the accuracy is second to none. The ranges lie from 0-300psi and 0-2100kPa.
The OTC 5605 Deluxe Compression Tester Kit is my premium pick product for you to buy. This device comes with a 25-inch flex hose compression gauge that is easy to assemble and quick to read. It is a complete test kit that can be great for gasoline-based engines. Moreover, you can get a reading range of 0-300psi and 0-2000kPa with the compression tester.
Nothing can match the value of the BETOOLL HW0130 Compression Tester Kit and what features you get with it. The tool kit comes with 8 individual parts that are quick to assemble and to use instantly. Having a 3-inch compression gauge with a color scale option is a great feature to spot the readings and the health of the engine. It includes a range of 0-300psi and 0-2000kPa.
