J57
AUTOMATIC REFRACTOMETER
The J57 Automatic Refractometer was designed
to meet the unique needs of industrial
environments where the refractometer is
operated on the factory floor. A single flat
measurement surface, electronic temperature
control and one button measurement
capability make it perfect for high wear and
tear, and heavy use applications.
- Refractive Index Range: 1.33-1.53
- Brix Range: 0-95
- Resolution: 0.00001 RI, 0.01 BRIX
- Electronic Heating and Cooling:
20°C or 25°C (Customer specified)
- Designed as a standard range refractometer
for primary use in industrial environments where
the refractometer is operated on the factory
floor.
