Semi-Automatic Refractometer ISAR-1000 Series used in the manufacturing center and production line seeking to maintain a high level of quality and adherence to stringent quality procedures, allow accurate reading of data and still require some manual adjustment to handle this equipment and measuring data rely on user skill. Provide accurate readout of the refractive index, %brix value, and temperature that display on LCD touch display. The ISAR-1000 series provide refractive index range, up to 1.30000 to 1.70000, resolution 0.00001 and brix range, up to 100 %, resolution between 0.1 and 0.01%, with temperature range 0 to 50℃ and -20 to -120℃. These refractrometer normally have RS232 and USB interface with a PC and are the instruments of choice for high-throughput labs seeking both accuracy and data integrity.
