Item #YE/2752, Wheatstone Bridges - Yokogawa
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
