Overview

The top-of-the-line J457 has many intelligent features built-in. The range is between 1.26 to 1.72RI and 0 - 100Brix. The accuracy is +/- 0.00002RI / +/-0.01Brix. The resolution is 0.00001RI and 0.01Brix. The temperature control range is between 10 deg C to 110 deg C and with temp. boost option it would be upto 120 deg C. This system would have an 8GB non-removable Compact Flast as internal memory.

Through the Smart Measure, the 457 has many intelligent features including Dirty prism detection, Incorrect calibration, Insufficient sample load, Cross contamination, Improper water zero, Trapped air bubble etc..

This system can also be made as a wall mount configuration in order to suit to production environments.

The 457 can also be upgraded with kits for Solids, Semi-Solids and Films.

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.


The J457 Smart Measure™ Advantage

Measurement problem:

alt

Sample residue is left on prism surface

Experience has shown that incorrect measurements are often linked to cross contamination caused by the previous sample being inadvertently mixed with the current sample being measured. Ensuring that the prism surface is properly cleaned between measurements can be difficult for busy environments where multiple operators are involved.

Smart Measure™ solution:Automated clean prism monitoring

Smart Measure™ knows when the prism is clean. If the prism surface does not produce the correct "Clean Prism" result then Smart Measure™ notifies the operator that further cleaning of the prism is necessary. Smart Measure™ notifies the operator that it is ready to measure after the prism is satisfactorily cleaned.


Measurement problem:

alt  An insufficient amount of sample covering prism surface

 A small drop of sample in the center of the prism will measure correctly. A large drop of sample completely covering the prism surface will measure correctly. A small drop on the perimeter of the prism will produce erroneous results.

Smart Measure™ solution: Automated sample load monitoring

Smart Measure™ knows when a sample has been loaded on the prism and immediately begins evaluating various metrics surrounding the sample load. If Smart Measure™ determines that those metrics indicate proper sample loading, it will display the result with a sample quality number. If Smart Measure™ determines that the metrics indicate an improper sample load, Smart Measure™ will ask the operator to clean the prism and re-load the sample.


Measurement problem:

alt Sample contamination or improper calibration

 An improperly cleaned prism, where sample residue is left in the measurement well, can mix with a water zero or calibration fluid. This type of contamination during the calibration process will cause an error across all subsequent measurements.

Smart Measure™ solution: Automated sample calibration inspection

Smart Measure™ is constantly measuring the prism surface and monitoring the value measured against its database of results. If during a water zero the instrument detects a value that is too different from the database or the RI value being input is far from the measured value, it will alert the operator.


Measurement problem:

alt The sample has air bubbles that affect measurement results

 Many samples have air trapped inside them or are carbonated. These samples read well most of the time as long as air bubbles are not trapped between the prism surface and the sample. When this happens the operator gets an erroneous result often referred to as a flyer. These results are called flyers because the measured value is quite different from the expected measurement value.

Smart Measure™ solution: Automated sample calibration inspection

Smart Measure™ catches these flyers by scanning the detector for varying RI values and then alerts the user to reload the sample. Since the user does not get a value to record until a new sample load is completed, Smart Measure™ greatly reduces the erroneous measurements from being recorded.


Smart Measure™ Features

Smart Measure™ knows when to measure and display a result even when the operator does not.Smart Measure™ Features J457 (all models)
  • Dirty prism detection
  • Incorrect calibration detection

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

alt

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.

alt


J457-WC Wall Mount Configuration

J457-WC Wall Mount Configuration is designed for production environments where water is used for cleaning or 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.

alt


J457-FC Factory Configuration

J457-FC Factory Configuration is recommended when there is a lot of sample 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.
