Refractometer vs hydrometer.

Postby newbiboozer » Wed Oct 16, 2013 10:45 am

Does anyone use a refractometer and is there any advantage over a hydrometer.

I wish...

still being pushed about with output abv by minor variations in ambient...

To use a refract would be an absolute goal...longer term.

Rather envious of a setup that's accurate enough to use.

Not sure how one would work on a finished wash and using a refractometer to calculate the percentage of sugar and then converting that to a gravity , yeah could be done for sure :handgestures-thumbupleft:
Might be a handy devise where unfermentables render the hydrometer useless (rum wash for instance)

I bought a cheap one off ebay for beer brewing but it is useless once fermentation is under way.
I'm not 100% on how accurate it is. It's supposed to have auto temp correction but it doesn't seem to match up with my hydrometer(s).

I haven't used it in ages :roll:

yes its basically for SG readings ei Brix/baume we used them in the vineyards to tell if grapes were ready to harvest and if the winery was happy with the reading in we went. They could be a useful tool if used for the purpose they are designed for, like I said the baume of things like fruit juice and rum washes where a hydrometer is nearly useless

I always thought the main purpose of a refractometer was so you could measure what the SG is when mashing to make sure you have hit the mark. I thought temp did not effect the reading :think:

Yeah that's how it is explained on some of them on eBay.

That what I was using mine for.
If it is not an Auto temp corrected one you have to calibrate it with distilled water at the same temp each time. (I use one for treating timber each day)
