The R-38 reichord bridge has been produced since 1953. The device is a balanced bridge with a stepped-adjustable shoulder ratio. The device is designed to measure the electrical conductivity of electrolytes on alternating current. The bridge is powered by AC power. The working range of the bridge is within 0.3 ... 30000 Ohms, which makes it possible to measure the specific conductivity of various electrolytes and is divided into 5 measurement limits, each of which is characterized by a certain resistance of the comparative arm of the bridge. The latter is made in the form of a set of resistances of 1, 10, 100, 1000, 10000 Ohms, switched on with a lever switch. In 1967, the device was upgraded with the same name.
