YOKOGAWA PRECISION DOUBLE BRIDGE 2769	Model 2769 is a compact, portable Kelvin double bridge designed for measuring low resistance from 0.1 ohm to 110 ohm with four multiplication plugs and one measuring dial. It has built-in standard resistors, bridge power source and high-sensitivity taut-band suspension system electronic DC galvanometer.	DC PRECISION MEASURING
YOKOGAWA PRECISION WHEATSTONE BRIDGE 2755	Model 2755 measures resistances from 1 Ω to 10 MΩ by operation of dials and switches. Batteries and a galvanometer are self-contained. The front control panel is provided with power and galvanometer circuit selectors, one ratio arm, and four measuring dials. Model 2755 is also equipped with a Murray and Varley Loop Tester for convenient location of line faults such as "shorts" and "grounds" in power, telephone, telegraph, and signal cables. No auxiliary attachment required Galvanometer with a built-in protection circuit Compact, lightweight (2 kg) Built-in Murray & Varley loop tester	DC PRECISION MEASURING
YOKOGAWA PRECISION DOUBLE BRIDGE 2752	Laboratory-grade accuracy ±0.03 to ±0.05% Quick readout without error Excellent long-term stability: The resistance elements are made of selected manganin wire, stabilized by both artificial and natural aging after being wound. Perfect guard system Stable measurement: The dial switches offer low contact resistance and little change due to aging, giving stable operation. Inner/outer contact type plugs are used for changing the multiplication factor, assuring little change in the resistance due to reinsertion of plugs. Built-in standard resistors Bar resistor measurement	DC PRECISION MEASURING
YOKOGAWA PRECISION WHEATSTONE BRIDGE 2768	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 shieldingMaterials 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 keysIf 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.	DC PRECISION MEASURING
YOKOGAWA DECADE RESISTANCE BOXES 2786	Models 278610 and 278620 six-dial decade resistance boxes allow quick and easy setting of a wide range of resistance. These resistance boxes are used in combination with voltage or current standards to adjust voltage or current, as dummy load resistances or as an arm of AC bridges.	DC PRECISION MEASURING
YOKOGAWA ELECTRIC GALVANOMETER 270710	Model 2707 is a compact transistorized electronic galvanometer using a battery. With sensitivity of 10 µV/div., this instrument is highly suited to field measurements and as an indicator for complex measuring instruments. 10µV div. Sensitivity Stable measurement Zero drift as low as 1µV/h or 1µV/20°C 300 hours battery life Overload protection circuit	DC PRECISION MEASURING
YOKOGAWA GALVANOMETER 270800	Model 2708 Galvanometer is a compact pointer type with a quick response (2 seconds). It employs a shock- and vibration-proof taut band suspension system.
