Brix 0-80%

This is a quality refractometer that works well. Great value.

Seems fairly well made and it works great. Very easy to use!

I now have three of these: a 0-30, which I use to judge when to move concentrating maple sap to the finisher, a 55-95, which I use to roughly judge near-finished syrup and also honey, and now a 0-80, just because. The first two are easier to read due to the narrower range (bigger numbers on the recticle), but the 0-80 is quite usable in bright light (all three have an adjustable focus on the eyepiece for vision correction). I have a big 7” calibratable Leader Evaporator maple syrup thermometer that is highly accurate for syrup sugar concentration (219 degrees F = 67.5% sugar +/-0.25% once calibrated to adjust for barometric pressure) and I find both the 55-95 and the 0-80 to be pretty accurate (+/-1-2%?). Not quite enough for production, but great to figure out when I need to pay attention. They are robust little buggers though I’ve never dropped one. I’m sure the $250+ models are much more accurate. But for my uses and at this price point, these are great. I just wish they weren’t made in China!

This product does a good job at getting close to your desired reading level. I use refractometers for making maple syrup. For my use I need a device for checking the sugar levels (brix) in the sap from the tree. This requires a device that reads between 0 and 10. With a 0-80 range it is hard to tell with any precision what the reading is at the bottom of the scale. As I boil the sap it will eventually cook down to syrup. The desired reading to know, for sure, that the sap has 'officially' become maple syrup is 68. Again, the 0-80 scale does not afford the precision I need. My recommendation would be to purchase 2 refractometers from this line. They make a 0-32 scale and a 58-90 scale. Both are much more precise than the 0-80 unit. Each of these is around $20.00.

Very easy method for gauging when maple syrup is concentrated enough. It only requires a few drops of sap or partially boiled sap to get an accurate reading. Will read as low as 0% Brix which is distilled water. Maple syrup is ready at about 60 to 65% Brix. The sap before any boiling down measured about 1.5% Brix. Since you get the full range you can check at any stage to see how much more boiling away is needed. For example, if it reads 30% Brix you need to boil until it is twice as concentrated and half the volume. When taking samples of hot boiling sap with the eye dropper you do have to wait about a minute for it to cool down before measuring, but it did not seem to affect the reading accuracy much if the liquid wasn't exactly at room temperature. To avoid getting air bubbles in the thin area between the glass plates it seemed to be helpful to lay the top plate down slowly and to apply the right amount of liquid. If air bubbles do get in, it seemed easiest to just start over by wiping clean and applying new drops of liquid. It is easy to clean between readings. I wiped surfaces with a damp tissue followed by a dry tissue to dry. Highly recommended for small-scale maple syrup making.

Works great. Very impressed with the accuracy. We used this and a separate hydrometer and both had the same readings.

This is soooo much easier for the small batch maple syrup producer! All you need is a few drops to check your sugar concentration from sap to syrup. Way easier, less expensive, and studier than a hydrometer and test cup! After checking, just the lens, dry with a soft cloth, and you are good to go. Love this!

Purchased this to test the brick of finished syrup and it is not accurate. Calibrated the unit with distilled water but it is still off. I find it reads about 6 points low. I verified with a thermometer and boiling water to find the syrup is done at 7.1 degrees higher and also a hydrometer. Was hoping it was more accurate.

Very handy and easy to use device! I use it to measure brix for maple syrup and my honey. It’s very accurate, easy to use and easy to read. It’s a good quality, feels good and sturdy.

Very accurate, easy to use. A few drops and you get a readout right away. This replaced my bobber - 100% better and faster. highly recommend. Solid construction. The only flaw is that the plastic pippette melts over 100 Celcius; you might want to use a glass pippette or just a simple stainless steel skewer.

Bought to use during maple syrup season. Worked well for the most part. Sometimes it fogged up a bit and the line went blurry, but it was still functional enough for an estimate.

Finally! Consistent quality for my backyard maple syrup production. Previously I was just eyeballing it based on colour and viscosity, with very mixed results. This little gizmo is a game changer. Easy to use and seems to give clear consistent results. Highly recommended.

Facile d'utilisation. Convient pour les acériculteurs. Donne une lecture précise du taux de sucre dans le sirop et autre.
