Anpro Brix Refractometer for Homebrew

Anpro Brix Refractometer is the best choice to replace your hydrometer for more precise measurements when brewing beer. Just use the dropper to put a drop of wort on the crystal. Then look through the eyepiece of the refractometer.

Anpro Brix Refractometer for Homebrew

 

The double scale assesses both Brix and Specific Gravity. Both are displayed, eliminating the need to convert to specific gravity. This is the suitable refractometer for homebrewers.

But accurate results require careful modification. The crystal and test should be at the same temperature. Don’t expose these refractometers to wet environments. Also, don’t submerge the refractometer. It becomes hazy under the light as water enters the body.

Note that you should avoid testing harsh or destructive synthetics with this refractometer. They can damage the coverings of crystals.

Anpro refractometer assesses the sugar contents of the brew and has a temperature range of 10 to 30 degrees Celsius.

This refractometer requires regular cleaning. Between each estimation, wipe the refractometer with a damp cleaning cloth. Inability to clean the crystal regularly leads to errors in determining reading and damage to the covering.

It’s an optical device. It requires caution and capability when dealing with this refractometer. Inability to do so can destroy optical segments and their actual construction. With care, this refractometer will provide support for years, which makes it worth your money.

Pros

  • A lightweight, compact in size, and portable refractometer, means you will love to carry it in your rubber jacket pocket
  • Easy to use and calibrate

Types of Refractometers

Traditional handheld refractometers, digital handheld refractometers, Abbe refractometers (or lab refractometers), and inline process refractometers are the four different types of refractometers. 

For home use, a handheld refractometer is preferable to a lab-style desktop refractometer. You can go analog or digital type.

i. Analog Refractometers

The cheapest choice is the analog refractometers. No power is required; place a few drops of the solution measured in the indicated location and hold the refractometer up to the light to read the scale. The disadvantage is that these models of refractometers must be accurately calibrated and held against enough light sources to obtain error-free readings.

ii. Digital Refractometer

Typically, a digital refractometer is substantially more expensive (we are talking thousands of dollars). They offer advantages, including an easy-to-read digital display and automatic calibration. To measure, add your liquid and then push a button to get an accurate reading on the digital display (As an affordable option, Milwaukee has a yellow LED display). The drawbacks of a digital refractometer are the initial cost and recurring battery costs.

 

Buying Guide for the Best Refractometer

Before you make your final refractometer purchase, keep the following considerations in mind. With these factors, you will be able to determine whether a particular refractometer is an appropriate choice for you, among a lot of others.

 

Performance

Without a doubt, your primary goal is to get the ideal balance of water and substances in your liquid. You want to guarantee that the procedure you follow is carried out precisely to produce the best output.

So, the first and most critical factor to examine in the store is performance. Read the description and product reviews of the best refractometers published on different sites to see what level of accuracy they promise. Do users express dissatisfaction with the calibration on any review site? Or does the manufacturer concede to minor plus-minus discrepancies in readings as recommendations?

You should be aware that you should avoid the majority of the refractometers of this type. Why compromise your effort on the fundamental function when you may acquire refractometers that deliver precise readings?

Check the temperature sensitivity as well. The standard temperature for determining concentration is +/- 20 degrees. In general, opt for the refractometer that has accurate measurement for temperature sensitivity.

 

Durability

Consider the materials used to make a refractometer when purchasing one. Choose those made of durable and high quality materials to ensure that they endure longer and feel solid in your hand.

It is also preferable to select a refractometer model that takes high-temperature changes without breaking. This is because refractometers are frequently exposed to either cold or too hot beverages.

Constant exposure to high temperatures might cause cracks to form and the refractometer to fail prematurely. Therefore, before making a final purchase, checking the durability that the manufacturing brand of the refractometer claims will be wise.

 

Usability

Another important consideration is the simplicity of use that a refractometer provides. You don’t want to waste money on refractometers with complicated controls and a slew of maintenance requirements that keep you busy unnecessarily.

Thus, the first thing you should consider is the design of the refractometer. Examine the power and control buttons to see if they are easy to read and understand.

Many refractometers contain controls that require you to wait from two seconds to a minute for something to happen. Consider this and decide whether you will be able to master such activities at the best time or not.

Similarly, most refractometers must be cleaned after each usage. Some cleaning methods necessitate the use of specific materials and chemicals.

 

Budget

Create a budget for yourself, considering your specific needs. Consider how much you should spend on a refractometer.

If you intend to use it frequently, our advice is that you spend as much as you can afford for the refractometers on the higher end (can cost more than a thousand bucks).  However, for beginners and infrequent users, paying as little as Milwaukee will be convenient, unlike the frequent users.

 

Refractometer Maintenance Tips

  • After each usage, cleaning the measuring prism with a soft, lint-free, and absorbent cellulose cloth is usually sufficient.
  • Water is a good solvent in most common circumstances. Ethanol or acetone, which eliminates oil or grease, is recommended for greasy samples.
  • The measuring prisms are the most sensitive parts of the refractometers. Thus, after measuring alkaline or aggressive samples, please clean the measuring prism and double-check the cleaning.
  • A disposable pipette or micropipette can be used to apply a small sample and cleaning agent.
  • Avoid the development of gas bubbles, as they affect the measurement and can lead to wrong results or differences in readings.

FAQs

Ans: It’s not that one is more “accurate” than the other. The only difference is a refractometer for measuring sugar content in a solution when light passes through the wort sample and then light bends through refraction. A hydrometer measures the specific gravity of wines or beers.

Ans: Although we recommend using distilled water, you can calibrate a refractometer with tap water only if it has reasonably low TDS (total dissolved solids).

Ans: A refractometer is accurate to within a scale of 0.2% Brix (0.2–0.3 %) when used properly.

Ans: For brewing beer or wine-making, add a few drops of your wort on the daylight plate of the beer or wine refractometer after making sure it’s clean and dry. If the wort is hot, allow it to cool to room temperature (ideally 68 degrees Fahrenheit) before proceeding. Close the sample plate, inspect for bubbles, and then place the refractometer in direct sunlight to refract better.

Ans: Brix Refractometers aims to use refraction to determine the sucrose content of a sample.

Ans: All five of our top picks deserve the crown. Personally, we like the Aichose Brix & Tiaoyeer Brix Refractometer.

Ans: If you want the most accurate salinity measurement available, consider getting a seawater refractometer rather than a saltwater refractometer,
