Precise measurement of the extraction level for perfect coffee

 

The DiFluid R2 Extract Refractometer helps you accurately determine how much coffee extract is dissolved in your drink. This is important for optimal control of the taste and strength of your coffee.

This is how the device works:

    • Take a sample: Place a small drop of coffee on the measuring surface of the refractometer
    • Measure: The device sends light through the drop and measures how the light is refracted
    • Read results: You can see the extraction level of your coffee in percent on the display

The DiFluid R2 Extract refractometer uses advanced digital refraction technology and is equipped with a carefully calibrated 2D CMOS image sensor, a micro-calibration layer, and two temperature sensors. All of this ensures very accurate measurements and high precision. You can connect the R2 Extract to the DiFluid Café app to analyse all data accurately and complement it with data from other DiFluid tools.

Key Features

 

  • Precise Measurement: Resolution of 0.01% with a precision of ±0.02% and an accuracy of ±0.03%; Measurement range of 0-30% TDS
  • 2D-CMOS Image Sensor: Reduces the risk of misalignments and fragility, improves data collection, and eliminates the need for a cap
  • Large Colour Display: Provides more details and additional testing options.
  • Aluminium Casing: Best thermal conductivity for stable measurements
  • Micro-calibration Layer: Compensates for external interferences and physical deformations, such as temperature changes or undissolved particles

 

 

  • Two temperature sensors: Minimize environmental influences by combining two separately placed sensors
  • Hydrophobic nanocoating: Prevents liquids from adhering to the glass surface, minimizes the need to touch the surface, and protects against scratches.
  • Water-resistant (IP67): Simply rinse and wipe the sample tray under water
  • DiFluid Café app integration for tracking, recording, and analysing data
  • Compact and handy
