DC PRECISION MEASURING
Yokogawa provides many precision instruments for calibrating and monitoring. Our line of Precision Bridges, Decade Boxes, Galvanometers, Potentiometers, and standard high precision resistors, allow customers the accuracy and quality demanded in a precision device.
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.
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.
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
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.
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.
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.
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. This unit is also suitable for classroom applications.
