Real-World Testing: Putting Sierra International 189900 Digital Compression Tester For Gasoline Powered Engines to the Test
First Use Experience
My initial test subject was, as mentioned, my 1998 Johnson 150 outboard motor. The testing environment was my garage, which while sheltered, tends to fluctuate from hot to cold and is usually dusty. I wanted to see how it behaved in those conditions.
The Sierra International 189900 proved remarkably easy to use right out of the box. The instructions were clear, and after a quick read, I was able to hook it up and start testing each cylinder. The back-lit LCD made readings easy to see, even in the somewhat dimly lit garage.
After the first cylinder reading, I knew this was worth the price. It was so easy to determine a low-compression cylinder, which allowed me to isolate the problem quickly.

After using the Sierra International 189900 for several months, I’m impressed by its durability. It’s survived accidental bumps and jostles in my toolbox without any damage. The tester maintains its accuracy.
Cleaning is a breeze; a quick wipe down with a clean rag after use is all it takes. The Sierra International 189900 has outperformed my previous experiences with analog testers. It provides precise and easily digestible data, streamlining engine diagnostics and repairs.
