The OPTi Digital Handheld Refractometer has been upgraded

Our best selling refractometers have been upgraded and it’s good news for all of our customers no matter what you measure.

The new OPTi® Digital Handheld Refractometer designed and manufactured by Bellingham + Stanley provides reliable and versatile measurement of total dissolved solids and blend ratios of liquids in a premium quality instrument. OPTi refractometers have always been a class leader when it comes to features and the new model retains everything you’ve come to expect, including a stainless steel prism dish, durable IP65 casing, long battery life and quick 2 second read time.

Now, in 2021, Bellingham + Stanley have taken the OPTi feature-set one step further and completely revolutionised the way in which digital handheld refractometers are supplied and purchased. Every OPTi Digital Handheld Refractometer now includes 50 common refractometer scales, giving customers access to scales including: the complete 0-95 °Brix scale, 1.33-1.53 Refractive Index, °Baume, Ethylene Glycol and more.

In addition to this vast library of scales, every OPTi now includes 3 selectable scales (A, B, C), which can be quickly switched between at the touch of a button, giving customers flexibility within their particular application. A refractometer with multiple scales can benefit users in many different industries. For instance, winemakers now have the option of using just one refractometer to measure Brix (%Mass) on scale A, grape must in °Baume on scale B, and alcohol by volume (by way of the Zeiss scale) on scale C. 

Switching scales is simple, and with the quick 2 second read time and pocket-sized form-factor, the OPTi refractometer is one of the quickest and most convenient ways to monitor and control your concentration on-the-go.
