Popis:	A shielded conductivity bridge employing direct balance to ground and variable ratio arms is described. The bridge as a whole is probably capable of an accuracy of about 0.01 percent over a range of one million ohms with greater flexibility than that of the customary fixed ratio‐arm conductivity bridge. The range may be extended to ten million ohms with only slight loss in precision. By using the two extra ratios provided in the ground arms the resistance of all solvents except those of lowest dielectric constant may be measured to a few percent on the same bridge.
