Salinometer.
Salinometer.
An ordinary form of marine salinometer is a graduated glass tube, whose bottom swells into two bulbs, the lower the smaller, and containing shot, to cause the instrument to float vertically.
The greater the degree of saturation, the heavier the liquid, and the consequent hight of the graduated stem relatively to the water's surface.
The water-chamber of Gamble's salinometer (Fig. 4550) is connected to the boiler, so as to give a constant indication of the degree of saturation, and contains a thermometer for showing the temperature of the water in the boiler.
The case has a glass face, through which the salinometer can be seen, and the bulb has a horizontal line, whose coincidence with one of the graduations at the side of the case shows the proportion of salt contained in the water, as 1 32, 2 32, etc.; intermediate proportions may be estimated b
