Salinometer, incomplete. It consists of a heavy copper tube or barrel with two pipes at the bottom. One pipe has a tap and serves as the boiler water supply, the vessel is filled and the excess water runs out of the vessel via an overflow to the second pipe. This makes it possible to measure a constant flow of boiler water, to determine an average. After the measurement, the water remaining in the vessel can be drained to the drain pipe by means of a second tap. A brass cylinder for the hydrometer (missing) and a thermometer are fitted in the vessel itself. A light and a round reflection mirror are attached to the outside on a hinged arm to enable reading of the salinometer in the dark boiler room. There is a mounting plate against the back. The inscription on the front has the English coat of arms., A.P. How (mentioned on object), London, 1850 - 1865, brass (alloy), copper (metal), glass, mercury, wood (plant material), h 56 cm × w 25 cm × d 13 cm
