Digital portable refractometers Refracto 30PX/30GS

Portable device for determining refractive index and derived concentration values. Simple operation and fast results: the sample is either dripped onto the measuring cell or the instrument is immersed directly in the sample liquid. Suitable for laboratory and field measurements, e.g. in food processing or industry.
  • Automatic temperature compensation
  • Suitable for measurement of dark samples
  • Backlit LCD display shows values and menu functions
  • Calibration with water
  • Memory for up to 1100 measured values, together with sample ID, unit, temperature compensation coefficient, time and date
  • Individual formulas for calculation of user-defined concentration data can be defined in the device
  • Measuring units: nD, nD temperature compensated, Brix% temperature compensated, HFCS42, HFCS55, °Baumé, °Oechsle (D, CH), °KMW (Babo), T.A. 1990, weight %, vol.-%, specific weight and freezing point (in °C or °F) for ethanol and NaCl, weight %, volume % and freezing point (in °C or °F) for ethylene glycol and propylene glycol, weight % and volume % for isopropyl alcohol, user-defined unit
  • Values can be transferred to the PC via IR interface

Refracto 30PX: Optical glass measurement cell
Refracto 30GS: Sapphire measurement cell for larger measuring range and faster temperature compensation
