  • Calibration Screwdriver
  • Calibration Solution
  • Plastic Pipette
  • Carrying Case

The Extech RF15 Sucrose Brix Refractometer measures the concentration of sugar in fruit juice and industrial fluids. Its compact size makes it easy to operate in small spaces and the prism and lens with its simple focus adjustment provides accurate and repeatable measurements on an easy to read scale. Accurate measurements can be taken using a mere two or three drops of solution. The Extech RF15 comes complete with a case, a calibration screwdriver, a plastic pipette and the calibration solution.

  • Sucrose: 0 to 32% Brix
  • Resolution: 0.2
  • Accuracy: ±0.2%
  • Automatic Temperature Compensation: 10 to 30°C

Easy to Use Professional Refractometer

Easy to Read Display

Measuring the concentration of sugar found in fruit juices or industrial fluids has never been easier thanks to the Extech RF15’s simple focus adjustment prism and lens.

Compact Design

At just 200 g (7 oz) and measuring a mere 6.6 x 1.6 x 1.2 inch (170 x 40 x 30 mm), the RF15 is easy to carry and stows away nicely in a toolbox or within the included carrying case.

Automatic Temperature Compensation (ATC)

Temperature is one of the single most important factors influencing accurate refractometer readings and is one of the largest sources of error in measurement. With the RF15’s temperature compensation feature, a correction factor is automatically applied to ensure accurate readings.

Measure Sugar Content for Consistency and Health

Whether you're producing wine, fruit juices, or carbonated beverages, using a Sucrose Brix Refractometer like the RF15 is vital for monitoring the approximate sugar content of the liquid and for maintaining consistency in the production process.

    It was a little lighter in weight than I expected so it didn't feel as solid as I thought it would. It was easy to hold and easy to use and gave reliable results. I'd recommend it for the price.

    This is an easy product to review. It was inexpensive to buy and it works. I've had it about 6 years now and I've "trained" lots of people to use it. Training takes about 3-5 seconds. The carry case does not close. It never did, but the refractometer works great.

    I couldn't get it to work properly. The description says the product doesn't need to be the same temp as the room, but the instructions do. It never gave me an accurate reading, resulting in super sweet or super sour product.

    Good unit from a good brand. Seems like the same quality level as that of the no-name brand units sold for a few bucks less in the industrial supply stores(theyr'e all made in China). The case/accessories/packaging may be better than some. This unit works well.

    This instrument has worked well for me for four years. I now rely on it for brix readings rather than the hydrometer, which is dependent on temperature and requires a much larger amount of wine, cider, etc. As for testing grapes for sugar content, it pretty much agrees with what my taste test tells me.

    I purchased this item 5-6 years ago. I use it once a year during grape harvest to take test samples of machine picked grapes and it has been accurate to .1 of a brix on every load that was tested. Taking your crop to a market that requires certain sugar standards in order to pass, this has been a highly valuable instrument and more than pays for itself after one season. Yes, I highly recommend this product, it has been extremely accurate in regards to the more expensive commercial type digital refractometers.

    In the absence of a handheld oscillating tube densitometer costing a few thousand more, this device matches my old school hydrometer to .050 points in accuracy.
    It works very well.
