Vaiseshika Electron Devices manufactures Senior Kelvin Double Bridge. Vaiseshika Electron Devices Quality Management System is ISO 9001:2000 compliant. The Senior Kelvin Double Bridge, Type 9403 is an ideal resistance measuring instrument. Applications include use 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 Senior Kelvin Double Bridge 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. The slide wire is totally immersed in oil to ensure total stability of resistance in the bridge.
