Sera Marin Floating Salinity Specific Gravity Hydrometer
Sera Marin Floating Water Salinity Specific Gravity Hydrometer Qty; 1 PC. Always check Water Salinity Specific Gravity. Floating glass hydrometer Extremely simple-to-use for fast and effortless testing Monitor and maintain Water Salinity. Extreme ease of use makes the standard floating hydrometer a classic favorite. Measuring Water Salinity Specific Gravity is as simple as the Sera Marin Hydrometer in your water Tank. Features measurement range of 1.000-1.040 with graduation increments of 0.01. Calibrated at 77 degrees Fahrenheit and measures 5/8 diameter x 6 - 1/2.
The salinity (salt contents) can be deduced from the measured density. Since the salinity of marine water in an aquarium must be kept constant, the aquarium water should regularly be checked accordingly. The water to be tested is filled into a sufficiently tall water glass, and the scale of the immersed hydrometer is read off on according to its immersion depth.
