Deluxe Manual Refractometer
A very handy, stainless device for measuring the moisture content of your honey. This is an accurate instrument that will provide years of use for an economical price. Measures BRIX% from 58 to 90 in quarter percent increments and Water% from 12.0 to 27.0 in half percent increments.
• Refractometers are useful tools, and this sturdy device is simple to calibrate. Calibration for refractometers is only accurate for temperature at which calibration is done.
• If the temperature of the room shifts 5° F, you must recalibrate. After this calibration, the instrument is calibrated for the current ambient room temperature.
All Refractometers are designed to measure the refractive index of a solution. The brix scale is based on a sucrose (sugar) and water solution. However, since most samples contain substances other than sugar--such as salts, minerals and proteins--the Brix percentage represents the total concentration of all soluble solids in the sample.
After measuring, use a lint-free tissue to wipe the sample off of the prism surface. If the sample contains oils or fats, use isopropyl alcohol and water to clean the prism surface.
When not in use, keep refractometer in the storage case at room temperature (68° F). Avoid storing the unit in direct sunlight or in a moist environment and do not subject the unit to strong shocks or vibrations. The ambient temperature at which you can safely store the units is between 40 and 104° F.
Hint: To prevent fermentation, honey must have a water content of less than 17% (safe regardless of yeast count).
Note: refractometers work on liquids only, so crystalized or creamed honey much be completely decrystalized first to get an accurate reading of its moisture content.
