The new digital refractometers in the DR7000 series contain an optical sensor, temperature control, measurement electronics and touch-screen display, all the components needed to reliably measure refractive index, %Brix or concentrations. The Operation is located directly on the device. A separate PC with software is not necessary.
The devices and their firmware guarantee high data security and meet all requirements for FDA-regulated areas (depending on the model), as well as for the European (Ph. Eur.) and American (USP) pharmacopoeia
