In-Line Process Refractometer

Model: GND15


GND15 In-line process refractometer is a refractometer that detects the Refractive Index of a sample and outputs , the Brix (%) value on the display , can also transmit measured data to external devices via 4-20mA or RS-232C. GND15 series has the function of automatic temperature compensation according to the temperature of the tested medium , when the tested medium temperature changes , the Brix value ( soluble solids ) after temperature compensation is displays and the output changes accordingly.



  • Automatic temperature compensation
  • Lightweight , compact and easy to install on site
  • LED display , easy to connect with other devices for automatic control
  • Easy to operate , only one transmission line solves power and data transmission
