This handheld honey refractometer reads Brix, Baume and water content from a single drop of sample, covering 58-90% Brix, 38-43' Baume and 12-27% water, with automatic temperature compensation. It is a purely optical instrument, so it needs no battery: you place a few drops on the prism, look into the eyepiece and read the scale where the light and dark fields meet.
Features and benefits:
- 3-in-1 scale: Brix, Baume and water content shown on one eyepiece scale, so you get three readings from one look
- Range of 58-90% Brix, 38-43' Baume and 12-27% water - suited to thick, high-sugar liquids such as honey, maple syrup and molasses
- Minimum division of 0.5% Brix, 1' Baume and 1% water, with a stated accuracy of the same size
- Automatic temperature compensation - no need to bring the sample to an exact temperature; the maker says to use it at room temperature between 0 and 30 degrees
- Focus adjustment on the eyepiece and a zero-setting screw for adjusting the reading against a reference solution
- Rubber grip and a compact 145 x 40 x 40mm body, weighing 0.1kg, so it fits a pocket or tool bag
- Supplied in a blue plastic carrying case with a dropper, screwdriver, user manual and cleaning cloth
Applications:
- Checking the water content of honey before jarring or sale
- Judging sugar concentration of maple syrup and molasses
- Beekeeping and small food production benches
- Teaching optical refraction and sugar measurement in schools and workshops
In the box:
- 1 x refractometer
- 1 x dropper pipette
- 1 x screwdriver for the adjustment screw
- 1 x user manual
- 1 x cleaning cloth
- 1 x blue plastic carrying case
Note: This is a manual optical instrument, not a digital meter. Set the reading with a suitable reference solution before use, as set out in the user manual, and wipe the prism clean straight after each measurement. The maker advises against leaving corrosive liquids on the prism for long periods.

A: A refractometer measures how much light bends as it passes through a liquid, which changes with the concentration of dissolved sugar. This one turns that bend into readings of Brix, Baume and water content on a scale in the eyepiece.. Q: How do you use a refractometer for honey? A: Place a few drops of honey on the prism, close the cover plate and look into the eyepiece while pointing it at a light source. Read the scale where the blue and white fields meet, then wipe the prism clean.. Q: How do you set the reading on a refractometer? A: Put a few drops of reference solution on the prism and turn the adjustment screw with the supplied screwdriver until the reading matches the value for that solution. The user manual gives the proper solution and reading.. Q: Does this honey refractometer need batteries? A: No. It is an optical instrument that works from daylight or a lamp, so there is no battery or power supply to manage.. Q: What does the water scale show on a honey refractometer? A: It shows the moisture content of the sample, from 12% to 27% water on this model, read alongside the Brix and Baume scales.. Q: Can it measure liquids other than honey? A: Its scales cover 58-90% Brix, so it suits other thick, high-sugar liquids such as maple syrup and molasses. It is not made for low-concentration samples below that range..
