A hand-held refractometer is a simple to operate, moderately priced
instrument that is suitable for field use. In most cases sample preparation is limited to
suitable dilution of a wet concentrate or blending of a dry concentrate with water.
Although many refractometer are temperature compensated to allow accurate readings
over a range of solution temperatures, they are sensitive to large temperature changes
to which they may be subjected during field work.
Any of several instruments used to measure the index of refraction of a substance. it is commonly known to be used in wine making, where the refractometer is used to measure the sugar content in the fruit juices.
Some labs store the refractometer with a piece of tissue in the prism assembly to keep the prism glass from being scratched.
An Abbe refractometer is an instrument used to measure the refractive index of a liquid, by utilizing the critical angle for total reflection.

One way to increase your reading rate is to practice timed repeated readings.
Yes, increasing your span of recognition can increase your reading rate.
To increase your reading plus level reading and answer the question and pick the best one and for close plus look at the number think about what can fit the line.
A refractometer measures the refraction of light through a medium. In beer manufacture it tests for the density of sugars in the beer and is able to tell you the sweetness.
