Oct 22, 2021 · Since getting into the hobby, I've been down the rabbit hole on salinity/specific gravity measuring devices. I've had the Hanna HI98319 Salinity Pen, a $20 Amazon White-Label …

Oct 29, 2024 · Vee Gee Scientific STX-3 Handheld Salinity Refractometer with ATC, Industrial-Grade, 0-100% Salinity Range, 1.000-1.070 Specific Gravity Range, 5-Year Warranty https://a.co/d/15uuDhd …

Oct 10, 2023 · A refractometer does not read accurately when alcohol is present. Fortunately, the equations for conversion to SG numbers are pretty accurate within 0.001-0.002 gravity units as …

Apr 10, 2009 · A few threads, and reading in the Wiki, have led me to believe that a refractometer is really only useful pre-fermentation to ensure that I'm hitting my numbers during the mash and boil, …

Jul 12, 2018 · A refractometer is likely a better choice than a hydrometer. Before the hydrometer crowd jumps in and claims that you can get perfectly good results using a hydrometer too, yes, that's also …

Nov 24, 2020 · For the refractometer only salinity matters right? or am I wrong? I was thinking really simple: 1. Callibrate refractometer with normal 35ppt reaction fluid. 2. Add 1L RODI water in bottle. 3. …

May 10, 2013 · I only use my refractometer when doing 1 gallon batches (because the volume required for multiple hydrometer readings at that scale becomes non-trivial). For my 5+ gallon batches, I just …

Mar 31, 2012 · I've been working on a web-based calculator to estimate %ABV from initial and final Brix. Yes, there are polynomials that allow OG and FG to be estimated from initial and final Brix, and then …

Dec 10, 2015 · Refractometer Calibration Assuming that a refractometer is made correctly for the fluid it is intended to measure, the way to calibrate a refractometer is to put a liquid of known refractive …

Nov 16, 2011 · A refractometer measures the refraction of light. Alcohol skews this, so the reading is useless once alcohol is in the mix. The hydrometer reading would be the correct reading if …
