Most refractometers rely on light for an accurate reading. Sometimes though when brewing the ambient light is not bright or consistent enough to clearly see the reading; what's a brewer to do? Our newest Refractometer with built-in LED light makes reading the gravity easy and fast, regardless of the lighting situation. Just place your sample on the lens, put it up to your eye, and click the light!
A refractometer measures the gravity of unfermented wort and wine must, and is a great device for both the home beer and wine maker. Refractometers differ from hydrometers as only a few drops are required for each sample. To use, simply apply 1-2 drops of your wort/must to the device prism (clear glass on the front), close the daylight plate (plastic cover) and press lightly so the liquid covers the entire surface, then look through the lens while aiming it at a light source.
NOTE: The picture of the read out in blue light, was taken on an iPhone while pressing the LED light button in a dark office. While the picture is not the clearest, when viewed with the naked eye, the reading is 100% view-able and easy to read.
This refractometer provides gravity readings in both Brix (0-32% +/- 0.2% accuracy) and Specific Gravity (1.000-1.120 +/- 0.003 accuracy). The device also has automatic temperature compensation (ATC) for temperatures ranging between 50-86 F (10-30 C), so no need for correcting the reading based on what temperature your liquid is - it does it for you. The readings will only be accurate before fermentation, as the presence of alcohol will throw off the calculation.
