Description
- The pocket sized digital refractometer that’s ready when you are. The OPTi Digital Handheld Refractometer from Bellingham + Stanley (pioneers of the handheld refractometer) is a highly reliable, premium quality instrument used to control the dissolved solids or blend ratios of products ranging from fresh fruit to industrial chemicals.
- Portable and precise Portable and simple to operate, the OPTi provides excellent “on-the-spot” concentration analysis with automatic temperature correction.
- The OPTi revolutionises the way digital handheld refractometers are supplied and purchased. With the OPTi refractometer you will have all of the scales you’ll need, right in the palm of your hand – no paying extra for high brix models. An onboard library of over 40 common scales including Brix, Refractive Index, °Baumé, °Butyro, Colostrum Quality, Wort, Ethylene Glycol % and many more can be swapped and selected at any time.
- Full 0-95 Brix Scale
- The Brix scale is the most common scale used in refractometry, yet many refractometers cover only a small portion of it. OPTi gives you more, with coverage of the full Brix range (0-95) at no extra cost.
- Over 40 Scales
- Each OPTi comes with 3 interchangeable scales pre-loaded from an onboard library of over 40 individual choices – meaning there are over 9880 possible OPTi combinations.
- Accurate one button measurement and a clear display presents reliable results, no matter who takes the reading. Thanks to its compact design and clever marriage of smart software and ergonomic hardware, OPTi refractometers are perfect for taking measurements anywhere.
- Covering the complete Brix range, a number of scale derivatives are available making the OPTi a perfect instrument for a wide range of applications whether measurement is required in the field or as a support instrument within the factory or lab.
- Full 0-95 Brix range (or equivalent scale)
- “Duo” scale models

As easy as 1, 2, 3:
- The choice of scale is yours. With up to 3 scales readily available at the touch of a button, the OPTi is the most versatile and feature rich refractometer on the market.
- Need Brix for one application, and Alcohol Probable for the next? No problem! Switching scales only takes a moment, and with a read time of 2 seconds per sample, the OPTi is one of the quickest and most convenient ways to monitor and control your concentration on-the-go.
Application:
- Food & Beverage: Used for testing the ripeness of fresh fruits such as grapes and tomatoes simply by squeezing a small amount of juice directly onto the refractometer prism. OPTi refractometers are used in the manufacturing of jam, marmalade, syrup and other high sugar content products as well as quickly testing for moisture in honey direct at the hive. They are ideal for testing finished juices and other soft drinks. Scales include: Brix, °Butyro, HFCS, Salinity, Water in Honey, and more.
- Beer & Wine: From home-brew beer to the microbrewery and beyond, our refractometers have been helping brewers for years. In the beer world, refractometers are used to measure Wort prior to fermentation as well as determining alcohol content. We supply OPTi refractometers to vineyards around the globe so that grape ripeness can be checked before harvest, sugar content assessed and alcohol content measured in the final stages of production. Scales include: Brix, Wort SG, °Baume, Alcohol Probable, Oechsle, and more.
- Industrial: Bellingham + Stanley’s industrial scales cover a broad spectrum of applications. A common scale used within the industrial sector is Glycol % – useful for engineers working on air-conditioners, heat exchangers or even pasteurisers. When using the Brix scale, refractometers can be used for fire fighting foam and industrial coolants. In the aviation industry there is a need for determining the concentration of aircraft anti-icing fluids. Scales include: Brix, RI, Calcium Chloride %, Ethanol %, Ethylene Glycol %, and more.
- Automotive: OPTi refractometers are able to test coolant fluids (measurable in either °F or °C frost protection) and battery acid, as well as AdBlue® (DEF) concentration – ideal for vehicle service centres, garages, car manufacturers and fleet managers. Keep your vehicles runing smoothly and safely with OPTi. Scales include: Brix, RI, Sulphuric Acid SG, AdBlue®, and more.
- Veterinary & Life Science: Bellingham + Stanley offer a selection of scales for veterinarians and farmers for testing colostrum, blood and urine samples taken from animals. Thanks to needing only a small drop of sample to give a clear and accurate reading, OPTi refractometers are perfect for measuring samples that are often difficult to obtain or, in the case of colostrum, being a valuable commodity. Scales include: Brix, RI, Colostrum Quality, Urine Specific Gravity, Serum Protein, and more.
- And Many More…: There are many more applications where OPTi digital refractometers can help you measure and control, and as such Bellingham + Stanley has developed over 40 different scales to support your business. Visit our website or speak to the Bellingham + Stanley Customer Care team today.
