Hello Maud, Even if the Alcohol is 100% purity which is unlikely, once you start adding your titrating fluid (1ml NaOH mixed into 1 litre water) there is water...
Even with 70% IPA we haven't had such great luck with it here. Like I said, even our extremely color-blind member is titrating with turmeric for that reason....
I have seen numerous ref to making good quality or bad quality bio. How does one determine between the two? What equipment is needed? Will bad bio harm an...

Hello Maud, Have you had experience with the Fuelmeister? Then I suggest he not buy a pH metre of dubious value, buy one with un- dubious value. Squire Tilly...
Thank you Maud and Tilly. I hadn't heard of the Warnquist test, so I will check that out. Compared to the $600 bill a lab estimated, $5 is great, five cents...
Hello Tom, I suspect when people say good and bad they really mean high conversion and low conversion. Many diesel engines do not require especially high...
Hei Jonatben. When you say that you might be able to help. Does it mean that you have capital availble for investing. I represent a norwegian company, that...
I've had a lot of experience trying to keep various brands of pH meters calibrated, and it's WAYYY more work and way less reliable than just doing a good...
Hello Kirk, I agree with Mark, If you can detect colour change you can not beat titrating with turmeric. Read the World Famous Chopstick Titration Technique...
I use a Hanna for testing dirt. Just wash it off and it works fine. They are built for field testing and abuse, not like the lab princesses. David Green ...
The subject of titration and colorblindness has come up a few times in the biodiesel world. Usually men are colorblind either red-green or blue-yellow (more...
I've done 100-125 titrations useing a milwaukee ph53. I check it against 10.01 buffer solution about every 5-10 titrations. It's just when I remember. I've had...
When you titrate with turmeric you do *not* evaluate shades of color. You evaluate a change from yellow to magenta/red. Whether you are color-blind or not, it...
My friend Karl is severely red-green color blind. The whole world to him appears in shades of brown. Karl can see the color change in a turmeric titration as a...
Hello Maud, A pH of 8.5 is the "Magic Number" in the titration. Actually it is Phenolphthalein that you just go to the first colour for 15- 20 seconds before...
-ok tks for the response. but now we have high conversion/low conversion. What does this mean? does high mean less sediment or liquid sediment or jelly...
Hello Kirk, Just to clear up a misunderstanding. I advised that you could do the titration with a pH meter because I thought you were colourblind. I know that...
I believe we're essentially saying the same thing, Tilly. Only here in St. Louis we go for a color change that lasts for 20 to 30 seconds. The reason...
Hello Tom, Conversion refers to how much of the Veggie oil is actually turned into biodiesel. If at least 98% of the Veggie oil is turned into biodiesel that...

Not long term without heating or solvent thinning to reduce viscosity, especially in a colder climate. Neither of these is considered biodiesel because the...
I do the tests to check for conversion However, the proof of good fuel is whether your engine likes it or not. To find this out you need to run an oil...

Thanks again, all. Sounds like turmeric and the Warnqvist test are worthy of tries. I will do that and report back. A pH meter is still attractive, though, and...
