Rudolph Research J457 digital benchtop refractometer

Monday, 03 March, 2014 | Supplied by: Scientific Solutions Pty Ltd

Rudolph Research Analytical has developed a refractometer with operational features that help users load and monitor sample quality. The J457 comes equipped with Smart Measure technology that automatically detects when the prism is improperly cleaned, insufficient sample is loaded or the instrument is improperly calibrated.

If the prism surface does not produce the correct ‘Clean Prism’ result, Smart Measure notifies the operator that further cleaning of the prism is necessary. Only once the prism is properly cleaned will the operator be notified that the product is ready to measure.

If the metrics indicate that improper sample loading has occurred, Smart Measure will direct the operator to clean the prism and reload the sample. Operator judgement is not required and eyeball alone assessments of sample load quality are eliminated.

Smart Measure is constantly scanning the prism surface and monitoring the value measured against its stored database of results. If during a water zero the instrument detects a value that is too different from the database or the Refractive Index value being input is far from the measured value, it will alert the operator that the instrument needs further calibration or cleaning.
