45 State Agencies have used Zeltex portable fuel octane analyzers over the years, making the ZX-101 series the gold standard in portable fuel testing.
The main way that fuel is analyzed is through a CFR engine, which takes time, costs a lot of money, and destroys the sample.
Our portable fuel octane analyzers are quick, preserve the sample, and the results are very close to the CFR engines.
Now the ZX-101SQ makes it even easier and more reliable to analyze fuel samples
where you need it most, when you need it most.
