The hydrometer function will test the salinity levels in marine aquariums and the thermometer will test the temperature of the water. This Hydrometer/Thermometer is easy to read and use.

Green color indicates both ideal temperature and salinity.

Hydrometer measures specific gravity: 1.000---1.060
Temperature in °F (40-120) and °C.(0-50)

Ideal water parameters:

Marine 22-26C

Salinity 1.020-1.024
