This model is handy for the testing of low sugar fruits and vegetables, Reamsian Bodily Fluids (per the Reams Biological Theory of Ionization), Maple Sap or for synthetic or semi-synthetic coolants. For machining and grinding coolants, please consult the Technical Data Sheet for appropriate concentration of fluid. This model is designed to give HIGHLY accurate readings with 0.10 Brix divisions (accuracy is +/- 0.10 Brix). This unit is TWICE as accurate as 0-32% models! All RHB models use ambient light, no battery or power source is required. Models with the “ATC” suffix are equipped with “Automatic Temperature Compensation” for accurate measurements without recalibration after shifts in ambient working temperature (field use). Included are: a pipette for dropping test fluids onto the prism (never dip the refractometer into the test fluid!), a mini screwdriver for scale calibration, and a Users Guide.

Priced competitively, but unfortunately the scale is very difficult to read

We used this refractometer to check our machine CNC coolant weekly. This is the 2nd one we have purchased and both have broken after about 2-3 months of use. The one we had before these lasted a couple of years. These are Not very durable or well built.

I purchased this tool specifically for checking the sugar content of sap from my maple trees. The comments highly recommend the tool for this purpose. The tool calibrates to distilled water at 68F and is advertised to have a "field' range from 50F to 90F. I had hoped to use it in the field so that I could determine which trees are "sweetest from year to year, however the tool reads about 2 percent too high. For a range of 1% to 4% (the range of my trees) this is unacceptable. What am I basing this on? For years I have used a sap hydrometer in the field and my field (outdoor) comparisons of the 2 tools shows the refractometer to be about 2% higher on average. When I take sap into the house (close to 68 degrees) the 2 instruments line up. This is supposed to be a temperature compensated device (i.e. the "ATC"). It appears not to be so, at least for the 50 degree range of my typical field needs, and I am not about to travel back and forth to the house for individual tree measurements. When it is 68 degrees outside maple season is over! I hope someone on the review board can provide advice.

Units work fine. No issues with anything.

Great price. I use it working with CNC machines. The solution we use as a rust preventative is non oil based and needs a 3.0 refract reading. So far this refractometer is accurate, easy to read, and use.

I bought this refractometer to measure sugar content in maple sap. I am a small producer and didn't want to spend a lot of money monitoring my RO. I did a test with 0%, 3% and 8% sugar in water. It was dead on once I set the zero correctly. The only negative comment I had was the manual was missing but everything else including the pipette and screw driver for adjusting the zero were in the case. I got it on sale for about $14 so I can't complain. The device seems to be well made and feels substantial in your hand.

Although I only have a few backyard trees (~10 taps), I really wanted to know if my ratio of sap/syrup was "within the norms." This refractometer is super-easy to use and extremely accurate. (I calibrated it with a 0% distilled water solution and tested it with a 5% lab sucrose solution. It was dead on at several different temperature tests!)The unit is also extremely rugged and seems well designed for field use. It also included a soft zipper case, two droppers, and a screwdriver for calibration. Although a precise instrument, I think this would easily stand up to long term use in the woods. You can also work it with gloves on - a bonus on those really cold days.I can only speak to the unit we received from the seller I chose (magnum_media). The seller also had fantastic customer service and answered my questions promptly.If you are producing maple syrup "for real" or just a hobbyist who loves data, this tool is for you. It is also great for when your friends and neighbors come over and want a "tour." I let them look through this and see how the sugar concentration can vary between trees - and even between taps on the same tree (I have giant 100 year old trees).Unfortunately, the only thing this tool cannot do is make my sap "sweeter." I found that my overall sugar concentration is 2%, which is pretty much normal. Oh well, I guess I can plant some additional trees and wait 100 years to see if they are sweeter.

We weren't sure what to expect from this instrument, as it seemed very low-priced. Thought it might be flimsy and poorly made. But that was not the case! This is a substantial, well made, easy to use refractometer. 0-10% Brix is pefect for measuring the sugar content of maple sap. The delivery time was very fast and it arrived in a well-padded case with instructions, cleaning cloth, and a plastic pipette. Very pleased with this purchase and have recommended it to fellow sappers.
