The Digital Pocket Tester is a portable, rugged, water resistant device that utilizes electric conductivity to determine the specific gravity/salinity of natural and artificial seawater. Within seconds, the salinity and temperature are measured and visually displayed on the easy to read backlit LCD screen.
Instant salinity reading
Salinity is a general term to describe the concentration of salt in water. However, there are always different salt content in the solution which is also known as different refractive indexes (salinity readings).
Dymax RF-20 Refractometer is a scale device that helps to read salinity of salt content in water by using a calculation of mathematical algorithm that relates the measured refraction against its concentration for a specific liquid. This device is made of high-quality anti-corrosion material that provides reliability and reads salinity instantly and accurately due to its high-resolution display focused to relevant range of reef aquarium.
