HONEY REFRACTOMETER

A Refractometer that every beekeeper can afford. Beekeepers are analytical by nature and we all need to know the moisture content of our honey. It only takes a drop of honey to put on the lens. You hold it in full sun and easily determine the moisture of your honey. Full, easy to understand instructions come with it. We have tested this unit side by side with the expensive models and they perform exactly the same. This is not a plastic tool; rather it is constructed from steel and will last a lifetime.

Why Use A Honey Refractometer?

Honey refractometers are used by beekeepers and honey packers to measure the moisture content of honey. Technically, refractometers measure the refractive index of a substance.

Explanation: Light travels at different speeds through different materials. The refractive index is just a comparison between two numbers: the speed of light through a vacuum and the speed of light through the material you are testing—in this case honey.

Light also changes direction after it passes through different materials. If you measure the difference between the angle of incidence (light coming in) and the angle of refraction (light coming out) of a substance you can use this number to determine the refractive index. This is how a refractometer actually works.

Explanation: If you look at a straw in a glass of water you will see it looks distorted. This is because light moves faster through just the glass than it does through the glass and the water combined. Likewise, light will move faster through honey that has few solids than it will move through honey that has many solids. In other words, the refractive index of honey will change based on the amount of solids (sugars and other substances) in it.

Refractometers also make corrections based on temperature, because the refractive index will change slightly as the temperature changes.

Now, to make this all the more perplexing, the amount of solids in a liquid is measured on a scale called the Brix scale.

Explanation: Brix is a scary sounding name for a simple kind of scale. Each degree of Brix equals 1 percent sugar. So, grape juice with a Brix of 18 is 18 percent sugar. The Brix of honey can be from about 70 to 88.

Now here is where confusion sets in. While most refractometers give a reading in Brix (solids in water),honey refractometers give readings of water in honey. This is (kind of) the opposite of Brix.

Explanation: This type of reading is used in honey refractometers so beekeepers don’t have to subtract the Brix reading from 100 to get the moisture level. It’s just a convenience. However, it can get really confusing when a beekeeper uses a refractometer designed for another purpose—such as brewing. Not only are these designed to be most accurate in other ranges, the readings are in Brix—not 100 minus Brix. It it best to use a refractometer designed for your specific purpose.

Once you understand how a honey refractometer works, it is simple to use. There are many variations in design, but these are the basic steps:

  • Calibrate the device with distilled or deionized water
  • Put a drop of honey on the prism
  • Close the trap door that flattens the specimen
  • Focus the eyepiece
  • Read the scale

Two things are especially important for getting accurate results:

  • Make sure the container of honey from which your sample comes is well-mixed
  • Take multiple readings, and average the readings

Explanation: Honey is a variable product which differs from hive to hive, even from cell to cell. And honey that sits for a while will have a different moisture content at the surface than at the bottom. So before testing, always make sure the honey is thoroughly combined.

Human error also plays a part. Sometimes a reading goes awry for no apparent reason and sometimes the scales are just misread or misunderstood. To be on the safe side, multiple readings are always a good idea.

One last thing: read the directions. All these devices come with detailed instructions which should be followed to the letter.
