Simple and precise optical instruments to analyse liquids and their solid contents. Models are equipped with an automatic temperature compensation device (ATC). Supplied with a plastic box and comfortable leather-type case.

Simple and sturdy instrument to measure the rotation angle of optically active substances. The measure in 180° is directly readable on two mechanical dials.

Light source: LED lamp (589.3 nm)
Polarimetiric Tubes one 100 mm and one 200 mm
Dust cover
Optical Glass Windows (4 pcs)
Rubber seals
Fuses

For measurement of various high concentration samples such as jam, marmalade, jelly, honey, concentrated juice or acidity and salinity. Ingress Protection class IP 65 means that they can be cleaned under running water. Easily calibrated since "zero-setting" (calibration) is achieved using water. Temperature measurement with Automatic Temperature Compensation. Various models for a variety of applications, e.g. measurement of urine, salt, sugar. With data transmission via near field communication (NFC).

Magnifier lens complete with articulated arm.

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
