2. Refractometry - Wikipedia

   en.wikipedia.org/wiki/Refractometry

   Refractometers are frequently used by grape growers and kiwifruit growers for Brix testing of sucrose levels in their fruit. Refractometry is also used in the gelatin industry. To convert the RI of a gelatin sol (reported in Brix) to a gelatin concentration, one need only multiply by eight-tenths (0.8). A sol with a 10.0 RI would therefore be 8 ...

3. Digital handheld refractometer - Wikipedia

   en.wikipedia.org/wiki/Digital_handheld_refractometer

   Digital handheld refractometers are generally more precise than traditional handheld refractometers, but less precise than most benchtop refractometers. They also may require a slightly larger amount of sample to read from since the sample is not spread thinly against the prism.

4. Brix - Wikipedia

   en.wikipedia.org/wiki/Brix

   Degrees Brix (symbol °Bx) is a measure of the dissolved solids in a liquid, based on its specific gravity, and is commonly used to measure dissolved sugar content of a solution. [1] One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. If the solution contains dissolved ...

   en.wikipedia.org/wiki/Refractometer

   Gemstone refractometers are available both as classic optical instruments and as electronic measurement devices with a digital display. [3] In marine aquarium keeping, a refractometer is used to measure the salinity and specific gravity of the water. In the automobile industry, a refractometer is used to measure the coolant concentration.

7. Abbe refractometer - Wikipedia

   en.wikipedia.org/wiki/Abbe_refractometer

   In the Abbe refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism. The refracting prism is made of a glass with a high refractive index (e.g., 1.75) and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism.

   Enter the Canon Pixma MG2522 all-in-one, currently on sale at Walmart for just $29. You'd be hard-pressed to buy a single ink cartridge for $29, let alone an entire printer.

9. Autorefractor - Wikipedia

   en.wikipedia.org/wiki/Autorefractor

   In some offices, this process is used to provide the starting point for the ophthalmologist or optometrist in subjective refraction tests. Here, lenses are switched in and out of a phoropter and the patient is asked "which looks better" while looking at a chart.
