  • Description

    All the accuracy you need in an easy-to-use handheld device

    OPTi® Digital Handheld Refractometer - A high performance refractometer with a vast choice of scales for a wide range of applications – all in the palm of your hand. 

    Software

    • Quick 2 second read time of sample
    • Onboard library of 50 scales
    • Up to 3 active scales on a single device
    • High Ambient Light (HAL) sensor detects and warns of too much light entering the sensor
    • Unique “AG Test Mode” that allows the use of long-life non sucrose based certified reference materials
    • Programmable read delay for sample temperature stabilisation 

    Hardware

    • Clear digital LCD display
    • Ergonomic & durable handheld design
    • IP65 rated
    • Easy-clean, stainless steel prism dish
    • Rapid temperature stabilisation

    The OPTi® Digital Handheld Refractometer is a high quality, UK made, simple-to-use, accurate, pocket sized refractometer offering measurement between 0-95 Brix and over 40 other scales.

    The OPTi refractometer is constructed using the latest manufacturing techniques. Stainless steel injection moulding to form the easy clean prism dish and ultrasonic welding to bond the housing. Each OPTi displays information to the user via and easy-to-read LCD display, helping to make readings even easier than using a standard optical handheld refractometer.

    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. 

    50 Common Refractometer Scales 

    Each OPTi comes with 3 interchangeable scales pre-loaded from an onboard library of 50 individual choices - meaning there are over 9880 possible OPTi combinations. 

    A Durable Design For Versatile Use

    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. OPTi is the refractometer that fits in your pocket. With a long battery life, true portability, and durable design: OPTi refractometers are ready when you are. Readings from an OPTi refractometer are clear and defined thanks to the bold digital LCD display. 

    All OPTi refractometers feature a four decimal place LCD display, Temperature Compensation (ATC), robust design with IP65 rating, a choice of three scales in a single device.
