J457 AUTOMATIC REFRACTOMETER

 

Smart Measure™ Technology Improves Results!

All J457's come with Smart Measure™ Technology that automatically detects when the prism is improperly cleaned, insufficient sample is loaded, or if the instrument is improperly calibrated.

Exclusive Dual Temperature Control System

All J457 models come with Rudolph's exclusive Dual Temperature Control System utilizing Peltier Technology. The J457 heats and cools the sample from both prism surface and sample cover. The insulating cover housing seals the Prism Well Ring to create a uniform temperature environment providing unmatched temperature control uniformity.

The J457 comes in three configurations to match your operating conditions

 

J457-SC Standard Configuration

is Rudolph's most popular configuration and provides an excellent combination of a small footprint and a large, easy-to-navigate touchscreen interface.

 

J457-WC Wall Mount Configuration

is designed for production environments where water is used for cleaningor there is a lot of sample spillage on the work surface. This configuration is also excellent for situations where there is very little work space available: out on the factory floor or in an over crowded satellite laboratory where there is little to no remaining bench space.

 

J457-FC Factory Configuration

is recommended when there is a lot ofsample spillage on the laboratory's instrumentation. Factories working with sticky resins and syrups that end up being spilled on the instrumentation are great candidates for the J457-FC as the measurement unit can be as much as six feet away from the display unit.
