Picture of a refractometer?

There are 2 main types of refractometers. One is an optical refractometer in which a liquid sample is placed on one end. The user then looks through the other end to get a reading. A picture of an optical refractometer can be seen here: http://www.sperdirect.com/mas_assets/full/300001.jpg The other popular type of refractometer is a digital refractometer. In this case the sample is placed on an optical reader and the digital refractometer displays a reading on an LCD screen.

How does a Refractometer Work?

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.






When refractometer reading increase?

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.

How do you use a refractometer?

Begin the calibration of your refractometer by lifting up the daylight plate and placing 2-3 drops of distilled water on top of the prism assembly. Close the daylight plate so the water spreads across the entire surface of the prism without any air bubbles or dry spots
