Can I use a refractometer to measure specific gravity?
641951
Hi, I use a hydrometer for measuring three things. The temp, alcohol content and the sugar content. I have used a refractometer in the past but not for wine. The one you would want to use is the Specific Gravity Refractometer for measuring alcohol. I feel they are however more expensive than an hydrometer plus this does all three necessary measurements. Hope this helps. Phil

Hello, Thank you fot the message. We asked this from the manufacturer and they told us the item might be work for measuring residual sugar. But there is no example before, Hope it works, Thanks

You would be able to get a measurement but I am not sure if the conversion from Brix to SG would be accurate since this refractometer is calibrated for wort.

Hi Aaron, thanks for your e-mail and question! The model number "RSG-100ATC' refers to a class of Chinese made 0-32% Brix and 1.000-1.120 Wort Specific Gravity Refractometers. While these units were groundbreaking in that they had the Wort SG scale on the unit, they were inherently flawed. Those units still use the "% Brix x 4 = Wort SG" linear formula to deduce the Wort SG - which is wrong. The "RSG-100ATCc" is a better unit in terms of accuracy when compared to the other units sold on AMAZON and eBay, but not better than the BREWfractometer and BREWfractometer Extreme (BREWx). The BREWfractometer and BREWfractometer Extreme (BREWx) are the most accurate Beer/Wine Refractometers on the planet. So our "RSG-100ATCc" is an amazing piece of technology - it is more accurate than most other units AND it is insanely inexpensive! Please note that the readings of Refractometers will be effected by the presence of ALCOHOL and become in accurate. Once fermentation begins, please use the readings in conjunction with an online conversion chart - Northern Brewer and Sean Terrill have ones that convert your FG (and almost FG) readings into useable info. Another thing to be mindful when using a Refractometer is to be sure that your sample has no grain grit or other solid particles. If light gets blocked by those sample particles, the reading will be hard see. For best results, use a strong light source and be sure that your sample is free from grit, pulp or debris. I hope that helps you out! We are here to help you brew better beer! Cheers!

It SAYS it's "calibrated for DOT 4 fluid only." You can still use it on DOT 3, but might want to cross check with test strips or a refractometer.

No, you need a Salinity Refractometer. Salinity Refractometer, Aquarium & Seawater - Dual Scale (1.0 to 1.070 S.G.) by Agriculture Solutions

Yes it will. You can set the units of measurement by ounces, mL, pounds, fluid ounces or grams with one touch of a button.

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!

Per the specifications from the manufacturer, this laser measure should meet your needs very well. It has a Built In Tilt Sensor - Displays 360° angle measurement in 2 axis allowing for accurate measure as well as Ten Measurement Modes - length, area, volume, angle, min/max, continuous, single indirect height, single indirect length, combined indirect height, and multi-surface are measurement for maximum versatility.

Yes the tool will measure any straight line distance as long as the end point has something to reflect on. If the far end of the distance does not have a surface I can reflect on I just have my co worker hold up a flat surface such as a clip board or any other flat surface within reach. They sell targets that I believe are magnetic if you are working alone. The glasses work quite well outdoors in bright sun if you are having trouble seeing the laser. It will not reflect off of glass.

This refractometer only reads Brix. However, there are a number of good calculators on the internet that will convert Brix into SG

Make sure the current sight is graduated at the correct distance. It should be fine.

Yes, its the same KIND of refractometer. However the scale installed in it is specific to coolants and battery acid specific gravity, not sugar concentrations.

yes, when I received my refractometer it was dead on. in the instruction you can test the refractor with distilled or RO water to calibrate the refractor.

depends on proximity. (the more ferrous mass the longer distance it will detect. less mass need to be closer)get detector as close to travel path as possible.

The one I have only shows the Brix from 0 - 32 in the display. It does not show specific gravity in the display.

Yes. You place it on the thing you want measured and zero it. Any angle. You may need a horizontal, or vertical, reference point.
