Abstract

471,790. Resistance measurements; compensating instruments for temperature errors. GRAVELL, J. H. Jan. 6, 1936, No. 10166/37. Divided out of 470,000, [Group IV]. [Class 37] Apparatus for measuring the electrical conductivity of a solution in terms of its concentration comprises spaced electrodes 11, a voltmeter 13 in parallel therewith, a manually adjusted impedance 15 to compensate for temperature of the solution; and a manually adjustable resistance 14 to compensate for variation in the conductivity of the solvent and for variation in line voltage employed. A switch 12 connects other electrodes 11<1> into circuit. An auto-transformer with tappings for tern. perature compensation can be employed instead of the windings 7, 8. Specification 372,916 is referred to.
