Salinity meter/salt concentration meter high precision (0-100 ‰) refractometer seawater specific gravity meter glass salinity meter

【Salinity Refractometer】This salinity tester is used to measure salinity of brine/seawater, monitor and control the concentration of saltwater. Ideal for aquariums and marine applications.

【Measures on 2 Scales】This saltwater hydrometer measures on dual scales: specific gravity and salinity. Ideal for aquariums, marine monitoring, agriculture, gardening and educational purposes.

【With ATC Function】ATC compensation Range (i.e. Built-in Automatic Temperature Compensation System) from 10℃ to 30℃.

【Solid and Lightweight】Salinity meter is made of durable aluminum, which is non-staining, non-corrosive and rustless. Also, it's compact in size with rubberized grip handle, very easy to carry.

Measurement is easy: Place a few drops of the liquid on the optical part of the refractometer, cover the prism, and the liquid will spread more easily over the prism, look throught the eyepiece against the light and you will be able to read the result value on the scale. 10℃~30℃ / 50F ~ 86 F. For temperature beyond this range, please calibrate before use.
