276800 Precision Wheatstone Bridge

Manufacture: Yokogawa
Product Description: Model 2768 is a Precision bridge used for the exact determination of resistance in the 100 m Ohms to the 110M Ohms Range with an accuracy of 0.01 to 0.05%. Since this instrument includes a high-sensitivity transistorized galvanometer and bridge power source, no auxiliary device is needed.
