Refractometers, hand-held, precision, MASTER-80H
For simple, manual measurement of concentrations and refractive indices of liquids. Hand-held, precision refractometers with focussing eyepiece, soft rubber eyecups (to reduce straylight ingress, also spectacle lenses do not slip off and are not scratched), case and conversion tables. Hand-held refractometers cannot be fitted with a thermostatic controller and so measurements have to be temperature compensated.

Models with extra code M: Basic model
Models with extra code T: with automatic temperature compensation (ATC)
Models with extra code a: with automatic temperature compensation (ATC) and protection class IP65
