Best Salinity Sensor For Aquariums

Salinity Refractometer for Aquarium Dual Scale Salinity Tester 0-100‰ & 1.000-1.070 Specific Gravity Saltwater Tester Brine Refractometer Hydrometer with ATC Function

DUAL SCALE - Salinity Refractometer measures on 2 scales: Specific Gravity 1.000 to 1.070 (D 20/20) and 0-1000PPT, which allow to get the both results at just one testing.
EASY TO USE - The aquarium refractometer need few sample, put 2-3 drops on prism and towards light source, you can get the the accurate readings quickly from eyepiece.
WIDELY APPLICATION - Brine refractometer can be used for measuring salt water, salinity of water and seawater, ideal for monitoring aquariums, Marine Fishing Keeping, Agricultural, lab experiment and Educational purposes.
ACCURATE & AFFORDABLE - Salt water refractometer features ATC (Automatic temperature compensation) function to ensure get consistently accurate reading. Easy to operate than traditional hydrometers and more affordable than digital refractometer.
DURABLE & PORTABLE - Saline (brine) refractometer is made of aluminium and rubber, non-rust, anti-abrasion and durable for long time use. Comes with plastic storage box, small screwdriver and cleaning cloth, easy to organize and carry with.
