GND In-line Refractometer (Room temperature application )



The In-line Brix-Monitor GND15 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 to 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 .
