Measurement range: nD 1.30000-1.72000; 0-95%Brix;
Temperature control range: 10-80°C

The DR7000 series devices are digital refractometers designed for measuring refractive index, %Brix or other concentrations in liquid samples. With an optical CCD sensor, Peltiertemperature control, measurement electronics, evaluation electronics and touch display, the devices contain all the components needed to carry out measurements reliably. The Operation is located directly on the device. A separate PC with software is not necessary.

The devices and their firmware meet all requirements for FDA-regulated areas (depending on the model), as well as for the European (Ph. Eur.) and American (USP) pharmacopoeia. The DR7200-P and DR7400-P models meet the requirements of CFR 21 Part 11.

MEASUREMENT
