Can this accurately measure 99.9% isopropyl alcohol..to see whether it is indeed 99.9%? Can it differentiate between 99.9% isopropyl and say, a 98% one? Thanks.

I'd say that this is more along the lines of a 'generally specific' more so than a 'literally specific' measurement. I'm sure you can find the right reading given enough time. This uses displacement to gauge the proof of a liquid so you'll have to be sure to let the hydrometer be free from the edges of its container and the water must be completely still. So yes, it will differentiate but you'll have to have a really good eye for it!

In order for a product to be labeled as 'alcohol free', it has to have less than .5% of alcohol in it. This pure vanilla is 100% alcohol free. I hope you purchase it and enjoy using it as much as I have. Thanks for your question :)

Yes it does give you a reading that is 3 digits right of the decimal. It claims to be that accurate, but I would have no way of knowing. I can tell you that every time I have measured myself, the reading seemed to be appropriate for the amount of alcohol I had consumed.

There are oz. and ml. marks, but with the shape of the bottle the measurement isn't 100% accurate. It is close though.

I would like the answer to that question myself. I have used this product for years, and when they began to describe it as non-alcoholic, I compared it to the kind marked as alcohol free. Same ingredients, same everything. I suspect they may need to label it as non-alcoholic for legal reasons, but that does not mean that it does contain alcohol, even less than .05 by volume. But I would like to be sure on this myself, so if anyone knows more about it than I do, please let me know. Jean Porter

The scale on the hydrometer reads from 0 to 100% of alcohol by volume and 0-200 percent Proof of Spirit. The hydrometer is for distilled alcohol only. It cannot be used for beer, wine or any other fermented beverage according to the label. There is also a temperature correction chart for temperatures reading below and above 60 degrees F.

Just looked at the bottle I have and there isn't any reference to the 1%. 99% pure works for me. Have been using it for years and I have a 90yr old friend who's been using it for 55yrs and swears by it. Sorry I couldn't help with the 1%.

Not many tests exist that are 100% accurate under any circumstance and this is no exception. Though through personal experience they have been accurate both when I thought I would be clean and also when I knew I wasnt. And like many others here. Take 2 back to back and compare results. Dont worry about the shade of the line, that doesnt matter...what matters is if its there or not. And this tests states that it tests up to 50...not 75 like another reponder.

It measures in either tenths or hundredths of ounces. Sorry I don't know which, but it is a decimal amount, because I use the grams. It seems to be accurate as far as I can tell, but a tiny bit slow on the read-out. If you need speed as well as accuracy, this isn't the one, but give it a second or two and read-out catches up. Good scale for the $$.

I'm not sure how to answer that question! It says 20% on the bottle; it works well; so i guess it is strong enough...

It works great on the original gravity reading. If you are making alcohol then you will need to convert the final gravity or use a hydrometer

I could very easily. Measure when you first make the broth then measure again when you feel that the process is supposed to be complete. It measures in % of alcohol and specific gravity, and may be on another scale. I have not played with mine as yet.

My best guess is NO. If it's not the same number it's probably not the same strength reagent. If you have the brochure that came with the kit, it explains that there are different concentrations of reagents and different strengths will give inaccurate results.

Daniel, If you're careful you should be able to do that. I use it to check the temperature of tea in a tea pot sometimes and it's right on the money with that. I'd recommend taking a couple readings on different spots and going with what seems to be the most consistent. Id also recommend pointing it at the label instead of the glass. You may in fact be reading the temperature of the glass - but it should be pretty close if not exactly the temp of the wine inside. Also, don't make the mistake of thinking the laser is the exact spot the temp is being taken. Place the larger opening on the gun directly on the bottle.

I just looked at the bottle and it doesn't state any percentage. Now you got me curious. Maybe we have to google the company and ask. Keep in touch.

Yes. Mine was the same. I think it 'a mostly alcohol which explains the consistency.

I will try. I don't think "pure" can be detected in DMSO. I've used it for years and have never experienced any kind of a problem with it; only success. "Concentrate?" I've never heard of it-concentrate that is. The DMSO bottle has always advertised 99% purity. I've believed that meant a little water was added to it. I know a number of people who use it - no side-effects whatsoever!!!!!Chet <><
