Nova-Tech X-Series Refractometers - Manual

z Largest & Sharpest Display Scale Available
z Exclusive “Zero-Ring” Requires No Calibration Tools
z Durable, All-Metal Design
VEE GEE ® X-Series Handheld Refractometers are exceptionally simple to operate
and provide quick, accurate measurements for the concentration of nearly any
aqueous solution.
Easy to Use. Operation 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 readings (see scale below left).
Accurate. Featuring the largest, easiest-to-read scale available with clear, sharp
figures, screen shading, and incredible contrast. These features significantly enhance
overall accuracy...even when several different operators use the instrument. All units
feature rubber grips on the body, which block the transmission of hand heat to reduce
temperature errors.
Compact & Portable. The small size of the X-Series models allows them to be used
anywhere...the field, plant, or lab.
Tool-Free Calibration. The VEE GEE ® exclusive “Zero-Ring” (patent pending)
eliminates the hassle of using a separate tool for calibration. Simply place a few drops
of distilled water or liquid standard (R.I. oil or prepared sucrose solution) on the prism,
turn the built-in “Zero-Ring” until the shadowline is at the correct value of the liquid,
and secure the set screw...that’s it!
Durable. The X-Series models feature rugged construction to provide years of reliable
use. The prism is mounted in an all-metal housing which allows the sample and prism
to reach temperature equilibrium quickly. Also feature non-roll stands to ensure that
once the units are placed on a table or bench top, they won’t be prone to roll off the
surface.
Wide Selection Of Scales & Ranges. Choose from Brix, Salinity, Refractive Index (nD),
and Coolant (freezing points of Ethylene & Propylene Glycol, Battery Charge Level).
Automatic Temperature Compensation (ATC). Models BTX-1, BTX-20, STX-3, CTX-1,
& CTX-2 feature ATC, which frees the user from having to re-calibrate in work
environments with large temperature swings. The effective compensation range is
10-30°C.
X-Series Models
Non-Roll Stand. Protects against damage
to the instrument when set down between
measurements.
Rubber Grip. Refractometers are greatly
influenced by temperature changes. The
rubber grip guards against the user’s hand
heat for accurate measurements.
Rubber Hood. Houses the focusable lens
and prevents light from entering through the
eyepiece during use.
Exclusive “Zero-Ring” For Calibration*.
Quick, accurate, tool-free calibrations.
*Patent Pending
Scale. The largest and sharpest
scale display available on a handheld
refractometer.
Prism Housing. Rugged, all-metal design
allows the sample and prism to reach
temperature equilibrium quickly. Daylight Plate. Exceptionally
durable with a double-hinge design
allowing even thick samples to be
easily measured.
Prism. High-quality optical glass material
ensures consistently accurate readings.
