Salinometer
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
Barometer is used to measure atmospheric pressure. Hydrometer is used to measure specific gravity.
The Greek scholar Hypatia of Alexandria is credited with inventing the hydrometer in the late fourth or early fifth century.
Salinometer
and what. air bubble system? or Hydrometer??
a hygrometer is used to measure the amount of Condensation as well as evaporation and a hydrometer is used to measure the specific gravity of liquids
A salinometer measures the amount of salt in something.
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.
a refractometerHydrometerIt is actually a salinity meterHydrometer is the most common tool used to measure salinity levels.
A salimeter.
Hydrometer measure the density of liquids.
It measured by the density of the size from the hydrometer.
We can use a salinometer.
For example concentration determination with a salinometer.
you can use range between 0.7500 to 0.8500
