2768 PRECISION WHEATSTONE BRIDGE
Model 2768 is a Precision bridge used for the exact determination of resistance in the 100 MΩ to the 110MΩ 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 required.

Superior resistor aliment
Minimized contact resistance
Guarding and shielding
Materials of high insulation resistance and low absorption are employed. Guard circuits are provided to insure stable operation even In highly humid atmospheres. The instrument is housed in a {grey} metal case to assure -to operator of excellent shielding.
Heat-insulated pushbutton keys
If the operator's body temperature were carried to the galvanometer sensitivity control keys, a temperature difference would arise at the contact point and produce thermal emf resulting in measurement error. To eliminate this effect, the pushbutton keys for the galvanometer sensitivity control are heat-insulated with phenol resin.
