Refractometer Catagories

What is refractometer?

[ 2014-8-24 ]

A refractometer is a laboratory or field device for the measurement of an index of refraction. The index of refraction is calculated from Snellí»s law and can be calculated from the composition of the material using the Gladstone-Dale relation.

There are four main types of refractometers : traditional handheld refractometers, digital handheld refractometers, laboratory or Abbe refractometers, and inline process refractometers. There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases.

In veterinary medicine, a refractometer  is used to measure the total plasma protein in a blood sample and urine specific gravity.

In drug diagnostics, a refractometer  is used to measure the specific gravity in human urine.

In gemmology, a refractometer  is used to help identify gem materials by measuring their refractive index.

In marine aquarium keeping, a refractometer  is used to measure the salinity and specific gravity of the water.

Refractometersales still supply all kind of refractometers, such asbrix refractometer and salinity refractometer.
