DR series digital handheld refractometers

Zastosowanie ręcznych, cyfrowych refraktometrów oszczędza czas, ponieważ pomiary kontrolne można przeprowadzać bezpośrednio na miejscu. Wyniki pomiarów są określane za dotknięciem przycisku i wyświetlane na wyświetlaczu.

Digital refractometer models available:

• DR101-60
  It is a basic model, with a measurement range of 1.3330-1.4419 nD and 0-60% Brix. Thanks to automatic temperature compensation for the Brix scale, a repeatable measurement result can be obtained even under changing environmental conditions. As a waterproof device, the DR101-60 meets the IP65 standard and can be cleaned under running water.

• DR201-95
  The DR201-95 compact handheld refractometer offers an extended measurement range of refractive index and sugar content of 1.3330-1.5318 nD and 0-95 % Brix. Automatic temperature compensation for the Brix scale helps the user measure beverages and sweet confectionery. The device is splash-proof and meets the IP64 standar

• DR301-95
  The R301-95 can measure refractive index or sugar content over a measurement range of 1.3330-1.5318 nD or 0-95 % Brix. In addition, the device measures salt content and allows for two additional freely definable scales. Automatic temperature compensation for the Brix scale can be connected as an option. A USB interface allows measured data to be transferred to a computer or printer at any time. An alarm option can be configured for monitoring limit values in production processes. An included AC adapter turns the DR301-95 into a small laboratory refractometer; for mobile use, powered by a 9-volt monobloc battery.

Typical applications:
The DR101-60, DR201-95 and DR301-95 digital handheld refractometers are ideal for the chemical, petrochemical, automotive, aerospace and food industries, as well as hospitals and pharmacies.
