Resource Description. A Refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).. There are four main types of refractometers: traditional handheld refractometers, digital handheld, laboratory or Abbe refractometers, and in-line process refractometers. The range of spheres of a given .Available refractometer styles include, from left to right, digital, handheld, and bench top, not shown to scale. Handheld and digital equipment are both used for field study. A digital refractometer can be brought in contact with a fluid and display a readout, whereas a handheld refractometer must be brought to the eye to read.Digital handheld refractometers; . details will be shared with OpenAI and retained for 30 days in accordance with their privacy principles. Please do not ask questions that use sensitive or . Digital Refractometers. Digital refractometers work on the same principle as handheld models but are software-based, using light from an LED focused on the usual prism. When the sample liquid is applied, some of the light which passes through this will hit a number of light-sensitive diodes to create the measurement line, which is known as the .
