Seawater Hydrometer

Product Code: RXSOL-61-2879-001

Size:

Color:

Product Short Description: Place the hydrometer into water, and let it flow freely in the water
Product Technical Specification:
Remarks:
A range of 0.990 to 1.040 kg/l, suitable for use in sea and fresh water and thus covering the range of densities normally required.
 
A scale graduated in density kg/l in air ( density in air is cometimes termed apparent density ) This permits the weight to be obtained by multiplying the scale reading by the volume in m3 of water displaced.
 
Calibration of the hydrometer for use in seawater, a liquid of medium surface tension.

Remarks:

Detecting free Iron :   Spray the surface with a solution of potassium ferricyanide. If free iron is present, a blue color will appear. This test is extremely sensitive and often gives false positive results, that is, it gives an indication of iron being present when it really is not. The ferroxyl solution must be made fresh each day by addition with Nitric acid. The ferroxyl tests are described in ASTM A380.


Ferroxyl indicator is a solution containing potassium hexacyanoferrate(III) and phenolphthalein. It turns blue in the presence of Fe2+ ions, pink in the presence of hydroxide ions, it can be used to detect metal oxidation. It is often used to detect rusting in various situations.

It can be prepared by dissolving 10g sodium chloride and 1g potassium hexacyanoferrate(III) in distilled water, adding 10 cm3 phenolphthalein indicator, then making up to 500 cm3 with distilled water.
