KRüss offers three models in its DR series of Digital Handheld Refractometers. The DR301-95 is the largest in this range; it is robust and suitable for everyday usage. Easily connected to a PC, allowing for measurements to be saved and evaluated at a later date, it incorporates the refractive index, sugar and salt scales, with the option to add two other user-defined scales. The DR301-95 offers more flexibility than most handheld devices – it can be easily calibrated, and has an optional temperature compensation feature. Add from the range of accessories the 9V power supply, and it transforms into a small mobile laboratory refractometer.
