In-line Process Refractometre (Long-Neck)

Model: CZ-L


CZ-L In-line process refractometre 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. CZ 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.
