BTX-1 Handheld Brix Refractometer

This Brix Refractometer Has the Largest and Sharpest Display Scale Available. The BTX-1 Handheld Brix Refractometers are exceptionally simple to operate and provide quick, accurate measurements of aqueous solutions. Typical applications are with concentrated fruit juices, soft drinks, industrial fluids, etc.

Easy to Use

The operation of this Brix Refractometer consists of placing 1 or 2 drops of sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the reading.


This refractometer features the largest, easiest-to-read scale available with clear, sharp figures, screen shading, and incredible contrast. These features significantly enhance overall accuracy... even when the instrument is used by several different operators. All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors.

Compact and Portable

The small size (roughly 1-1/2" x 1-1/2" x 6-1/2") of the X-Series models allows them to be used anywhere... the field, plant, or lab.


Features rugged construction to provide years of reliable use. The optical glass prism is mounted in an all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. Non-roll stand keeps instrument from accidentally rolling off table or benchtop.

Automatic Temperature Compensation

This feature frees the user from having to recalibrate in work environments with large temperature swings. The effective compensation range is 10 to 30°C (50 to 86°F).
