In-line Refractometer
(Intrinsically safe type)
Model : GND15 (B)
Description
The Intrinsically safe In-line Refractometer GND15(B) it designed to 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
RS485 . GND15(B) 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.
Thank you for purchasing our Intrinsically safe In-line Refractometer. This instruction manual is designed to guide
you to understand the functions and characteristics of the sensor. Before using the instrument, please read this
manual carefully to ensure safe and correct use. Please keep this manual for future reference
