SENIOR KELVIN DOUBLE BRIDGE

Model : 55X-SK

DESCRIPTION:-

“RAI Senior Kelvin Double Bridge” Model:- 55X-SK is an ideal resistance-measuring instrument. Instruments used in cable, transformer and wire manufacturing industries. This instrument is also suitable for the quality control and maintenance of transformers in heavy electrical engineering and power transmission projects. The instrument features a versatile range of 0.02 micro-ohms to 1.1 ohm. This is the only instrument, which provides measurement techniques of high precision for extremely low resistances. Ten standard resistors drawn from manganin sheet, each having a value of 0.001 ohm are provided in the bridge. The slide wire is divided into 500 divisions to provide a resolution of 0.02 micro-ohms. This slide wire is totally immersed in oil to ensure total stability of resistance in the bridge.
