Heathrow Scientific 43036 Handheld Refractometer, STX-3, 0 to 100 ppt Salinity, ATC, 1/pk

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. This salinity refractometer 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, this refractometer can be used in outdoor environments without the need to re-zero. The patented "Zero Ring" eliminates the hassle of using a separate tool during zero calibration. The rugged construction of this salinity refractometer 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.
