GND In-line Refractometer (high temperature Application)



The In-line Brix-Monitor GND15-H 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 RS485 .
GND15-H 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 . This product is designed for medium and high temperature (90~150 °C) applications . with a water cooling device, one is the water inlet pipe and the other is the water outlet pipe, through the water circulation to reduce the temperature of the liquid contacting our mirror, which can solve the impact of excessive temperature on the product accuracy and the damage to PCB .
