Electronic Digital Refractometer takes Measurement to a New Level

Rudolph Research Analytical’s Smart Measure™ Technology takes refractometer measurement to an entirely new level. The Rudolph Research J457 digital, benchtop refractometer actually monitors sample load quality, which assists the user in properly loading samples with a resulting increase in consistency and accuracy.

The Rudolph Smart Measure™ technology actually 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. Only once the prism is properly cleaned will Smart Measure™ notify the operator that it is ready to measure, so the operator can continue.

Rudolph’s Smart Measure™ detects when a sample has been loaded on the refractometer’s 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 reading. If Smart Measure™ determines that the metrics indicate an improper sample loading has occurred, Smart Measure™ will direct the operator to clean the prism and re-load the sample. Operator judgment is not required and eye-ball alone assessments of sample load quality are eliminated.

Rudolph’s 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.

Smart Measure™ knows when to measure and display a result even when the operator does not. User error is greatly reduced and measurements can be utilised with additional confidence.
