Vaiseshika Protable Weatstone Bridge

We are offering vaiseshika protable weatstone bridge.
Description
"vaiseshika" portable wheatstone bridge type 9401 has been specially designed for the measurement of resistance in the range 0.01 ohm to 1.0 megohm. The resistance measurement spectrum provided in the equipment is coupled with excellent accuracy of the order of ±0.05%. These exquisite capabilities have been realized in this equipment by using non-inductive imported manganin wire (german make). In addition, precision phosphor-bronze silver plated band switches have been utilized to minimise the contact resistance errors to 0.0005 ohm per switch. The manganin coils have been subjected to long ageing process to eliminate the possible variations in the resistive value due to climatic temperature variations. All the coils have been properly insulated with high grade insulation material to arrest the variation in the values.
