OPTi® Digital Handheld Refractometer
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.
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.
Versatile
Thanks to its durable design and vast range of scales, the OPTi is suitable for
a wide range of applications; from the clinical laboratory to the harshest
of environments.
Digital Display
Readings from an OPTi refractometer are clear and defined thanks to the bold
digital LCD display.
Ready when you are
The refractometer that fits in your pocket. With a long battery life, true portability, and durable design: OPTi refractometers are ready when you are.
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.
• Quick 2 second read time.
• Onboard library of over 40 scales.
• 3 active scales on a single device.
• High Ambient Light (HAL) detection warns of too much light entering the sensor.
• Clear digital LCD display.
• Unique “AG Test Mode” that allows the use of long-life non sucrose based certified reference materials.
• Durable IP65 pocket sized design.
• Programmable read delay for sample temperature stabilisation.
