REV X Super Tester Flex Fuel Ethanol E85 to E10, E15, E20, E25 Test Kit

La graduación es una etiqueta pegada, si lo manejaran con graduación grabada directo al mismo recipiente te estaría mejor..

Fait son boulot mais prix excessif

Seems expensive for what it is..I’m quite sure you could make one of these yourself but it would be necessary to have a good quality bottle and a way to calculate the ratio and get it marked on the bottle: Short version is this works well , fast and accurate. I’m amazed at the difference in premium gasoline and regular!!

Thanks to Amazon I got my money back otherwise it would have been £25 down the drain. Some Einstein at their warehouse decided to put an adhesive product sticker right over the read off label which itself is a VERY poorly adhered sticker onto what is a VERY poor quality plastic bottle. Seriously You are better off just getting a 100ml glass measuring cylinder, the type used in school chemistry labs, and using one of those. I reported this to the seller and whilst they apologised there was no offer of a replacement or refund so once again thanks Amazon.

Makes it easy to test and get an accurate ethanol percentage when mixing different blends. Works well, just wish the cap opening was a little larger to pour into. Still a solid and reliable tester.
