Description of 🐠 Hallocool Salinity Refractometer: Advanced Aquarium Saltwater Tester with ATC - Dual Scale 0-100 PPT & 1.000-1.070 Specific Gravity - Ideal for Marine Fishkeeping Hydrometer Testing
DUAL SCALES - Saltwater Refractometer measures on specific gravity (D20/20) 1.000-1.070 and parts per thousand 0~100‰ (1‰=1ppt=1000ppm), allow you to get the result in two different units by one test. WIDELY APPIICATION - Seawater Refractometer designed for Aquariums, Marine Monitoring and measures salt water or salinty of water to help you to control concentration of salt water. EASY TO USE - Put 2-3 drops of sample solution after calibration on prism, towards light, then get the accurate readings. Hallocool aquarium refractometer is ideal for replacement salinity hydrometers or expensive digital salinity tester. ATC FUNCTION - Salt water refraactometer can automatically compensate for changes in the ambient temperature, minimize the impact of temperature on accuracy and allow you obtain results faster and easier. DURABLE & PORTABLE - Saline refractometer is made of aluminum and ABS rubber, anti-rust, non-staining and resistant abrasion, sturdy for long time use. Portable refractometer with plastic case easy to carry.
