Abstract
<PICT:0759056/III/1> A method of determining, in a continuous masher the degree of oxidation of sulphurous gas in the manufacture of sulphuric acid by the lead chamber or intensive processes includes as a characteristic feature measuring the potential assumed by an electrode immersed partly in said gases and partly in water in contact with said gases. The device may be connected to alarm relays or servomechanisms capable of directing the process of manufacture. Thus a receptacle 1 through which the gases flow in at 7 and out at 8 comprises a horizontal tube with water inlet and outlet tubes 2 and 3 respectively and constant level along line A, B maintained by constant head device 4 and containing a neutral wire, e.g. platinum, acting as an electrode which is wound around insulating support 5 in the form of a U with one limb above the other below the level of the water. A second reference electrode 9, e.g. calomel, is placed in tube 10 traversed by the feed water and the potential is measured by connecting to a suitable choice at terminals 11 and 12.
