• MEASURES ON 2 SCALES - Seawater Refractometer features specific gravity (D20/20) 1.000-1.070 and parts per thousand 0~100‰ (0~100PPT), allow you to get the result in two different units by one test
• WIDELY USE - Salinity Refractometer designed for measuring salinity of water, salt water, ideal for Aquariums, Marine Monitoring, agriculture, fish-keeping, saltwater pools
• EASY TO USE - Put 2-3 drops of sample solution after calibration on prism, towards light, then you get the accurate readings through the optics eyepiece, ideal for replacement difficult to read hydrom
• ATC FUNCTION - Saltwater refractometer with automatic temperature compensation (ATC) function, minimize the impact of temperature on accuracy and allow you obtain the accurate result faster and easier
• DURABLE & PORTABLE: salt water refractometer is made of aluminum and ABS rubber, anti-rust, non-staining and resistant abrasion, durable for long time use. Portable Refractometer comes with plastic ca
