The SmartRef Digital Refractometer by Anton Paar is a portable smart pocket device suitable for a wide range of requirements. The SmartGuide+, as a feature in the mobile app, automatically checks any errors of ambient light, impurity, and sample behavior during measurement for you. The device offers more than 15 different measurement units with automatic temperature compensation. Depending on your need SmartRef enables you to measure the salt content of your aquarium or pool, the extract content of your beer, the sugar content in wine, the sweetness of fruits and vegetables, the moisture of honey, and much more.
Applications:
- Beer Brewing
- Wine Making
- Bee Keeping
- Saltwater Aquarium & Pool
- Fruit and Vegetables
- Jam and Jelly
- Ketchup and Dips
- Industry
- Automotive
Features:
• Wide measuring range from 0 to 85 °Brix
• Accuracy of 0.2 °Brix
• Built-in wort and alcohol correction for beer that is fully configurable
• Quick readings – results in under 2 seconds
• Automatic temperature compensation (ATC)
• Small sample volume (0.4 mL)
• Free iOS/Android app
Smart Brewing Refractometer
-
Wort Plato and Specific Gravity readings are automatically adjusted
- Built-in wort correction factor is applied and can be configured completely
- Alcohol correction can be applied to all readings when alcohol is present
- Fast temperature stabilization and automatic temperature compensation (ATC) of the measurement results make additional calculations and correction tables obsolete.
- The Brew Meister app enables ABV calculation based on your OG & FG, easy storage, visualization, management, and sharing of measurement data.
- In addition to the quick measurement mode, measurements in continuous mode allow a more detailed understanding of the samples’ properties.
Smart technology for consistent results
- SmartGuide+, as a feature in the app, detects and helps to eliminate any measurement problems through high ambient light detection, continuous check of prism and sample condition, and more.
- The SmartRef is used in combination with a free mobile app for Android and iOS via Bluetooth Low Energy and enables intelligent handling of the measurement results.
- Over-the-air updates keep your digital refractometer up to date with the latest features.
SmartRef measurement details
- The SmartRef refractometer measures the refractive index of fluids. This allows to retrieve relevant sample properties in a wide variety of applications.
- Fast temperature stabilization and automatic temperature compensation of the measurement results make additional calculations and correction tables obsolete.
- The unit has an IP66 rating and an easy-to-clean stainless steel sample well.
- The SmartRef supports a one-point zero adjustment with distilled water and requires only a few drops of sample (0.4 mL).
- It displays results in under 2 seconds and has a measurement range of 0 to 85 °Brix with an accuracy of 0.2 °Brix.
High variety of measurement applications
-
Honey, wine, juice, sauces, jams, fruits, vegetables, and maple syrup
The SmartRef measures the sugar content in °Babo, °Baumé, °Brix, °KMW, and °Oechsle. -
Saltwater aquariums and saltwater pools
The SmartRef determines the salt content in your saltwater aquarium and pool in Salinity Specific Gravity (SG 20/20), Practical Salinity Units (PSU), and Salinity in Parts per Thousand (ppt). -
Beer
The SmartRef shows the extract content of wort in °Plato and Specific Gravity (SG 20/20). -
Industry & automotive sector
The SmartRef determines the freezing point and concentration of ethylene glycol and propylene glycol. - And more
As a smart device, the SmartRef offers a constant expansion of measurement units. All available scales are provided within the app.
