Salinity refractometers with premium optics and smooth focusing, aluminum main body. The internal optical lens of the salty tester refractometer with high refractive index to ensure the measured values more accuracy and clear scale for reading easily

Features:
Aquarium saltwater refractometer with ATC function, can automatic compensate for changes in ambient temperature, allow you get the accurate results quickly and easily
Dual scale refractometer for aquarium, provides readings of 0-100‰ (0-100PPT parts per thousand) and corresponding specific gravity 1.000 to 1.070, get the result at just one test
Brine refractometer is designed for measuring the concentration of saltwater, seawater, salinity of water, to help you to monitor and control the concentration of aquarium or marine fish salt water
Salinity meter refractometer is very easy to use, just need 2-3 drops of solution after calibration, then get the accurate results, more convenient than a conventional salinity hydrometers and affordable than a digital salinity refractometer
Salt water refractometer is widely used for aquariums, marine monitoring, agricultural, gardening and education purpose

Specifications:
Dual scale range: Specific gravity (D 20/20) and parts per thousand 0-100‰(0-100 PPT),
Mini scale 0.001 (1‰)
