Handheld Salinity Analog Refractometers

The refractometer’s unique design provides exceptional control and precision. It features the largest, easiest-to-read scale available, with clear figures and incredible contrast to enhance accuracy. The built-in Automatic Temperature Compensation (ATC), with a range of 10 to 30°C, ensures that your measurements are accurate without the need for manual temperature correction. A tactical, non-slip rubber grip on the body helps block hand heat, further reducing temperature errors. Its patented "Zero-Ring" calibration system simplifies the process, and the entire unit comes as a complete kit with a carrying case and a one-year warranty.

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.

A salinity refractometer measures the concentration of salt, such as sodium chloride, magnesium and calcium sulfates, in liquids and displays the results. Monitor salinity in seawater, ponds, aquariums, fish farms and holding tanks.
