Is this calibrated for beer brewer's wort, or for a sucrose solution, thus requiring dividing by a wort correction factor of 1.04 when brewing beer?

I do believe this one is purpose-made for brewer's wort. I have used mine only once and found it to be quite accurate.

This refractometer is calibrated to show both degrees of Brix and Wort specific gravity. I use it post mash soak, per oil and post boil for Gravity. Next I use it for terminal gravity after fermentation

The fermometer will light up with either 2 colored boxes(green & brown I think) or three. If it's only 2 colors, then the temp is between the even numbers, ie if 66 & 68 are colored, then the temp is 67. If there are three colors(blue,green,brown, I think) then the temp is the middle color. For example if 66, 68, & 70 are colored, then the temp is 68 degrees. This works much like that of a mood ring, it's extremely easy to read once you see it in action. Since it is only labeled in even numbers, the color code is necessary. Good luck with your brewing, you can't find a better way to keep your temps:)

As long as it is a liquid, if there is alcohol in the liquid i know it will not give an accurate read (usually too high). These are intended to be used before fermentation. I would suggest getting a hydrometer and plastic cylinder for more accurate readings. Typically you will need around 10-12 fluid oz to fill the cylinder and get a reading. A hydrometer is around 8-10 bucks usually

This meter's pH scale doesn't vary much above and below 7.0. Most people have a liquid available at the store they can use to do a quick check, distilled water, which under ideal conditions should have a pH of 7. If the scale is off by even a factor of .5, it could really hurt your plants.Some basic chemistry calculations: Kw = [H+][OH-] = 1x10^-14 at 25°Cfor pure water [H+] = [OH-] = 1x10-7Acidic Solution: [H+] > 1x10-7pH = log10[H+]Basic Solution: [H+] < 1x10-7When calculating pH, remember that [] refers to molarity, M.

The one I purchased had both BRIX and SG however, I believe the SG is an approximation based on a conversion from the BRIX scale. Still, it's good enough for the beer I make :-)

One Brix is one gram of sucrose in 100 grams of solution, or 1% w/w or w/v, assuming water is the solvent. 1 tsp of sugar weighs about 5g and 18 oz of coffee is about 30ml, therefore about 17 Brix. So, yes you should be able to use this refractometer for this purpose. Blank the device to water and check the coffee reading and blank the device to unsweetened coffee and measure the sweetened. There is likely to be some refraction reading from the coffee alone versus water and variation between batches of coffee.

Sean, I have purchased many BAC testers over the years and have yet to find one that does not require calibration. Because they have a sensor built into them, over time or heavy use, the sensor will need to be recalibrated. The Breathometer says calibration is recommended after 250 uses which is in line with others in the market (typical range from other products is usually 100-300 uses). A nice feature here is that there is a test count in the app allowing you to keep track.

I honestly don't know an exact answer to yer question as i've never made that. I use the Champagne yeast as it yields the highest alcohol content in my beer!

Comparing against a floating ThermoHydrometer in wort, this refractometer is accurate within .001 SG. I use a hydrometer to check for FG. THis is a very accurate tool, and you can adjust the focus to get precise readings, when paired with a conversion chart one can quickly determine the specific gravity of wort without having to worry about temp adjustment.

No calibration required. Just keep the test tubes clean. Works great by the way.

I use mine for brewing. It is not instant - a good reading takes 5 - 10 seconds. I had a different digital thermometer get gummed up by the steam from the wort. This one seems to be unaffected by it. This is a good thermometer if you don't need instant temps.

Virtually. There are trace amounts of alcohol from the brewing process. Less than 0.1% though.

within ±.001. Has easy to use calibration adjustment and instructions. Great for Original Gravity. For subsiquent gravities go on line and find a converter for readings with alcohol. This is URL for the one I use: http://hickorybrewer.com/index.php/brewtools/brix-correction-calculator/

As Mark said NO, it is fixed at C. However, I only use the temperature readings to make sure my calibration solution and my rinsing solution are at the same temp. Speeds up calibration. You have to press the C button to get the reading and as soon as you let go it goes back to pH. My cell phone has a C to F conversion when necessary.

It does not require calibration, but it sometimes under-weighs by .1 ounce. I bought a set of 1 oz and 2 oz weights and test it occasionally, especially when I get a reading that is exactly 1, 2, or 3 ounces.

Off the top of my head I think it needed a 1:1 ratio with water (1 part G12 to 1 part water). Its best to use denatured or distilled water for best results.

I would not want that much head space for a one gallon recipe unless I was expecting a large amount of foam up from the ferment. I started off with one gallon batches for experimental brews, but now do 2.5 gallon instead. Why? It usually turns out pretty good and am sorry I didn't make more.
