## What is MecaTest?

Introducing MecaTest: A new Approach for Engine Compression Evaluation.

Are you concerned about your engine's true condition? If you're experiencing power issues, excessive oil consumption, or unusual exhaust smoke, your engine's mechanical health may be to blame!

Are you considering purchasing a vehicle? Don't rely on looks alone when buying a vehicle.

The relative compression test is a great tool to assess the mechanical condition of your engine.

What is a relative compression test?

The principle of the relative compression test is based on tracking the battery current waveform during the cranking phase.
Analysis of the current waveform gives the comparative compression values of all cylinders. An engine with poor compression in one or more cylinders can be quickly identified using the relative compression test.
The compression magnitudes are expressed as percentages, with the highest magnitude labeled as 100%. If the difference between the maximum and minimum compression values is less than 20%, the application considers the engine to have passed the test.


How does MecaTest work? 

MecaTest is an innovative mobile app that transforms the way you assess relative engine compression.
MecaTest utilizes your iPhone's magnetometers for tracking the battery current  during the cranking phase.
No additional sensor required! Say goodbye to tedious tasks like dismantling intake manifolds or spark plugs.
Mecatest conducts a comprehensive relative compression test, comparing cylinder to cylinder.

Why Mecatest is so innovative?

This app provides a simple, cost-effective, and efficient solution. Gone are the days of relying on extra sensors or deciphering complex charts.
MecaTest offers a convenient voice-guided option, ensuring you can easily perform the test on your own, connect a bluetooth speaker or headphones, turn on the timer and follow the instructions!
MecaTest works for truck, tractor, boat... engines and is compatible with 3 to 6-cylinder petrol and diesel engines and streamlines the process, making engine compression evaluation accessible to everyone.
