WebThe Abbe refractometer is the standard instrument for measuring refractive index of rigid lens materials. This instrument determines the critical incidence angle of a light beam to achieve total internal reflection. The internal reflection is correlated to the refractive index of the optical material. WebMeasuring urine specific gravity (USG) is an important component of urine analysis as it evaluates renal concentrating capability. The objective of this study was to quantify the difference in USG values between a hand-held optical analogue refractometer and a cat-specific digital instrument. Urine samples from 55 cats were assessed.

Refractometer Definition & Meaning - Merriam-Webster

Webrefractometer: [noun] an instrument for measuring refractive indices (as for identification or the determination of sugar content). In drug diagnostics, a refractometer is used to measure the specific gravity of human urine. In gemology, the gemstone refractometer is one of the fundamental pieces of equipment used in a gemological laboratory. Gemstones are transparent minerals and can therefore be examined using optical methods. See more A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the index … See more There are four main types of refractometers: traditional handheld refractometers, digital handheld refractometers, laboratory or Abbe refractometers (named … See more • Brix • Oechsle scale • Plato scale • Baumé scale See more • Sella, Andrea (November 2008). "Abbé's refractometer". Chemistry World: 67. See more Standard refractometers measure the extent of light refraction (as part of a refractive index) of transparent substances in either a liquid or solid-state; this is then used in order to identify a liquid sample, analyze the sample's purity, and determine the … See more Automatic refractometers automatically measure the refractive index of a sample.
