  KRÜSS DR6000 Series

  

  Digital laboratory refractometers DR6000-TF fully automatic

  In addition to the Peltier element, the DR6000-TF models have a flow-through cell which, in conjunction with the drying unit, peristaltic pump and autosampler, enables fully automatic operation. The measured value is determined using a CCD sensor.

  These refractometers are the ideal solution for manufacturers of flavors, fragrances and essential oils, as well as for the pharmaceutical and beverage industries. They are ideal for routine analysis with high sample volumes, quality and purity control of raw materials and end products, or determination of sugar concentration in juices and soft drinks.

  KRÜSS DR7000 Series

  

  Digital laboratory refractometers KRÜSS DR7000-Series

  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.
