Vee Gee Scientific STX-3 Handheld Refractometer, with Salinity Scale, 0-100, 1.0

Description

Vee Gee Scientific STX-3 Handheld Refractometer, with Salinity Scale, 0-100, 1.0
[
"Handheld portable refractometer for measurement of salt concentration in parts per thousand (PPT) (0 to 100%) and specific gravity (SG) (1.000 to 1.070) of seawater in the 10 to 30 degrees C temperature range",
"Automatic temperature compensation (ATC) for immediate and accurate calibration readings, regardless of ambient temperature",
"Ambient light illuminates the scale; no additional power source is required",
"Durable metal and rubber outer shell with a telescope-shaped, streamlined design (40 x 40 x 185mm), a rubber grip to guard against hand heat for accurate measurements, and a non-roll stand to protect against damage",
"Optical glass prism mounted in all-metal housing for quick temperature equilibrium between sample and prism"
