More About this Item

These compact benchtop refractometers are ideal for measuring Brix, salinity, and refractive index with the full scale accuracy of 0.1%. The internal CCD scanner (linear scanned array imaging) provides accurate, reliable measurements. Units are simple to use – place at least 0.4 mL of sample on the surface of the prism, press READ, and the sample results are displayed in seconds. The meter instantly displays the measurement and temperature on the large, easy-to-read LCD.
The sophisticated microprocessor provides automatic calibration, automatic temperature compensation, low-battery indicator, automatic shutoff (after three minutes) and visual hi/low alarms. The durable, water-resistant design protects the electronics in wet environments and makes cleanup easy. All models calibrate to distilled water and feature a simple push-button interface and 5000 reading battery life.

  • Q:

    Can this be used to measure sucrose?
    Asked on 10/20/2014 by QA Tech from Indiana

    1 answer

    • STAFF EXPERT

      A:

      Yes. Brix is the sugar content of an aqueous solution. Each % Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. If the solution contains dissolved solids other than pure sucrose, then the % Brix only approximates the dissolved solid content.

  • Q:

    The specifications state that the instrument is accurate to .0002 but the display shows 3 digits. How is a result of .0002 displayed?
    Asked on 4/1/2014 by Ken from United States

    1 answer

    • STAFF EXPERT

      A:

      The picture is showing the measurement in % Brix. It is accurate to .0002 in RI units.

  • Q:

    How does the unit display 4 digit refractive index measurements?
    Asked on 4/1/2014 by Ken

    1 answer

    • STAFF EXPERT

      A:

      This instrument is extremely accurate, with an accuracy of plus or minus 0.002 RI units, so the resolution reflects this. It can display more than four digits on it's display at a time.

  • Q:

    Can this be used with glacial acetic acid?
    Asked on 11/18/2013 by NFL

    1 answer

    • STAFF EXPERT

      A:

      This unit should be fine measuring the acetic acid. We can not guarantee long term exposure chemical compatibility but the unit should be just fine for quick measurements.

  • Q:

    Does this model have a digital output display for Refractive Index?
    Asked on 7/30/2013 by R&D Tech from New York

    1 answer

    • STAFF EXPERT

      A:

      There is no output analog or digital - simply the digital display. I was not able to find a benchtop unit with an output, but the inline refractometers have outputs. For example, please see part number 81005-25.

  • Q:

    How is the system affected if there are particles in suspension within the media?
    Asked on 7/16/2013 by Phil the tech from Southampton, England

    1 answer

    • STAFF EXPERT

      A:

      Digital refractometers are not affected by the suspended solids content, dye concentration or viscosity of the solution compared to the Abbe type of refractometer. So, this is the preferred type of refractometer for food & beverage, wine making, automotive, and many other industries.

  • Q:

    How do you calibrate this product?
    Asked on 10/15/2012 by ptdexter from New York

    1 answer

    • STAFF EXPERT

      A:

      Clean the PRISM WINDOW before and after every use.
      • Fill the PRISM WINDOW with a standard solution such as
      distilled or deionized water. The ideal temperature of the
      solution and the unit should be 65°~72°F (18°~22°C).
      • Close the COVER.
      • Press the ON/OFF button to turn the unit on.
      • Press the ZERO button for 3 seconds.
      • When the procedure is complete, CAL will be displayed.
      • To check the nD value, press the ZERO button once.
      • This data can be viewed at any time to show the last calibration
      value.
      • A flashing crosshair symbol is displayed when the calibration
      solution falls outside the accepted range.

  • Q:

    It is possible to measure RI of organic solvents?
    Asked on 7/12/2012 by Hector from Mexico

    1 answer

    • STAFF EXPERT

      A:

      With the exception of highly corrosive chemicals, this unit should be fine for use. Please note that we cannot guarantee the compatibility with all organic solvents / chemicals; but this unit is designed to be quite durable for testing many different compounds.
