🌊 Master salinity like a pro—precision that travels with you.
The Vee Gee Scientific STX-3 is a rugged, handheld salinity refractometer designed for professionals demanding accuracy and durability. It measures salt concentration (0-100% PPT) and seawater specific gravity (1.000-1.070) with automatic temperature compensation for instant, reliable readings. Its industrial-grade metal body with rubber grip ensures long-lasting performance, while ambient light illumination eliminates the need for batteries. Ideal for scientific, industrial, and aquatic applications, it comes factory-calibrated with easy field calibration and includes a carrying case and pipet for on-the-go precision.
