Digital handheld refractometers DR301-95
Digital handheld refractometers 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 salt content 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.
