Cole-Parmer® Digital Refractometers

Never wait for readings again

These digital refractometers feature an LCD, eliminating reading errors with common handheld refractometers. All models feature built-in automatic temperature compensation (ATC) which removes temperature fluctuations allowing the user to concentrate on the measurements. The compensation range is 41 to 104°F (5 to 40°C).
Many range options are available for measurements within any application. All models also feature a zero% adjust with distilled water, allowing for immediate and easy calibration for precise measurements at all times. The battery life for these units is ≥5000 readings.
