DSHD-QX-D Octane Cetane Number Tester

1. Summary
DSH D -QX-D Octane Cetane Number Tester our new product, developed for testing Octane number for all kinds of gasoline(Such as aviation gasoline, motor gasoline, blending gasoline, ethanol gasoline and methanol gasoline ) and  Cetane number & Cetane index for diesel.
It is suitable for mechanized troops, oil refining enterprises, oil storage and distribute company etc to test octane number or cetane number quickly.
