$Digital handheld refractometer DR101-60$

DR101-60

As an entry-level model for the digital refractometry, the DR101-60 covers the measurement ranges between nD 1.3330–1.4419 and 0–60 % Brix. Thanks to the automatic temperature compensation for the Brix scale, you can achieve reproducible measurement results even under changing environmental conditions. As a water-tight device, the DR101-60 meets IP65 code and can be cleaned under running water.

$Digital handheld refractometer DR201-95$

DR201-95

The compact handheld refractometer DR201-95 offers an extended measurement range of the refractive index and the sugar content of nD 1.3330–1.5318 and 0–95 % Brix. The automatic temperature compensation for the Brix scale helps the user with the measurements of beverages and sugary confectionary products. The device is splash-proof and meets the IP64 standard.

DR301-95

$Digital handheld refractometer DR301-95$

As a mobile handheld device or digital tabletop unit, the DR301-95 can measure the refractive index or the sugar content within a measurement range of nD 1.3330–1.5318 or 0–95 %Brix. In addition, the device measures the salinity and allows for the use of two additional freely definable scales. The automatic temperature compensation for the Brix scale can be optionally connected.
A USB interface allows you to send measured data to a PC or a printer at any time. An alarm option can be set up for monitoring the limit values in production processes. The provided mains adaptor turns the DR301-95 into a small lab refractometer; for a mobile use it is operated with a 9 V monobloc battery.
