Handheld Salinity Refractometer

The STX-3 Handheld Salinity Refractometer features the largest, easiest-to-read scale available with clear, sharp figures, screen shading and incredible contrast. This significantly enhances overall precision, even when several different people use the refractometer. The STX-3 also comes with a rubber grip on the body, which blocks the transmission of hand heat to eliminate temperature errors.

With an automatic temperature range of 10 to 30°C, the STX-3 can be used in outdoor environments without the need to re-zero. All measurements are automatically compensated to 20°C. If measurement values shift, zeroing the STX-3 is very simple. The patented "Zero Ring" eliminates the hassle of using a separate tool during zero calibration. Simply place a few drops of distilled water on the prism and turn the "Zero Ring" until the scale is zeroed and secure the setscrew...that's it!

The rugged construction of the STX-3 will 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. The non-roll stand ensures that once the STX-3 is placed on a table or bench top, it won't be prone to roll off the surface.

Each order comes with a 5-year warranty & includes a zippered vinyl carrying case, plastic transfer Pipette, and instruction manual.
