The digital hydrometer for sale is an electronic hydrometer for measurement of liquid density, specific gravity and salinity. Hydrometers have high precision. SG range can reach 1.000~1.071. The measurable salinity range is from 0 to 100 PPT. Hydrometers price are affordable, widely used in industrial or civil production such as aquarium, alcohol, wine or beer brewing.
The digital water tester combines the functions of salinometer and TDS meter for water quality, salinity, TDS (PPM), and temperature measurement. As a TDS tester (total dissolved solids meter), its PPM measurement range can reach 0~10000. As a salinity meter, the measurable salinity range can select 0.01% ~5%, 0.01% ~10, 0.01% ~15%, and 0.01% ~25%. The salinity and TDS meter price is reasonable. With fully functional, beautifully designed, small in size, waterproof and dustproof, it is ideal for commercial and household use in aquarium, drinking water production, TSD online testing, etc.
