Salinity Refractometer, Automatic Temperature Compensation Handheld Hydrometer 0 100 ppt & 1,000 1,070 Specific Gravity ATC Refractometer for Sea Water Aquariums

Precision measurement: sharp separation line (blue-white), good readability (daylight detectable), adjustable eyepiece for focus adjustment. Designed for testing the concentration of salt water and salt solution, ideal for aquariums, marine monitoring, aquaculture fish, shrimp, crab, coral, etc. and quality control in research and clinical laboratories. Easy to use. Place 2-3 drops of sample on the main prism, close the plate and look through the viewing window to read the salinity value. Our chrome-plated brass body is resistant to chemical corrosion and wear-resistant, the life of the refractometer is increased several times than other aluminium housings. Measuring range: salinity 0-100% (0-10% salinity), density 1000-1070 SG, accuracy: salinity +/-1%, density +/- 0.001 SG, accuracy: ± 0.2%.
