Liquid Analysis for Every Application
Beer
Measure wort extract in Plato or specific gravity with automatic wort correction and monitor fermentation with alcohol correction.
Wine
Measure must weight in grape must and wine using Brix, Baumé, or Oechsle, supporting fermentation monitoring and quality control.
Coffee
Analyze coffee strength using total dissolved solids (%TDS) to refine extraction and maintain consistent flavor profiles.
Industrial Liquids
Measure blend ratios and concentrations of samples like heat transfer fluids and cutting oils for process and quality control.
Honey
Determine honey moisture and sugar content in %water and Brix to ensure freshness and reduce spoilage from microorganisms.
Pet Health
Measure the urine specific gravity of cats and dogs for health screening and check colostrum quality in Brix for newborn animal care.

Safety Information
The Measurements You Need, When You Need Them
SmartRef delivers fast concentration analysis from a handheld device. From beer wort extract, to fruit sugar levels, aquarium salinity, honey moisture, coffee TDS, and even the concentration of heat transfer fluids and cutting oil – you get accurate readings across 40+ built-in scales. Automatic temperature compensation and built-in corrections save time on calculations, while an IP66-rated housing and a stainless-steel sample well make setup simple.
Smart Technology That’s Made to Measure
Pair with our free mobile app for iOS and Android to store, visualize, manage, and export results with ease, while keeping your data backed up across devices in the Meister Cloud. SmartGuide+ prevents measurement errors, detecting ambient light issues, and checking prism and sample status in real time. With both quick and continuous measurement modes, you gain instant results and deep insight into sample behavior.
Any Sample, One Device
With SmartRef, you can analyze must weight in wine, track sugar content in juices, fruits, and syrups across multiple scales, or monitor aquariums and pool salinity. SmartRef tracks wort extract and determines coffee strength via in-app extraction yield calculator. Technicians can check antifreeze mixtures, freezing points, and cutting-oil dilution ratios. There’s even support for urine specific gravity for sports monitoring or animal health.

What is the measurement principle of SmartRef?
SmartRef is a digital refractometer that measures the refractive index of liquids. Refractive index is a dimensionless value that indicates how fast light travels through a sample compared to vacuum, and it varies with temperature.
How do I clean the SmartRef?
After your final measurement of the day, rinse the sample well with distilled water and dry it using a soft tissue.
Can I fill in a hot sample into the sample well?
Yes. The SmartRef has a temperature range for samples of 10 to 100 °C.
