Xtester- ZX74 - ZX77 Series DC Resistors precision multi-value DC resistors

The ZX74 - ZX77 (ZX74E - ZX77E) series DC resistors are precision multi-value DC resistors. They are suitable for scientific research institutions, metrology departments, universities, and industrial and mining enterprises for electrical measurement and other experiments. In DC circuits, they are used for precise adjustment of resistance and can be used for calibrating DC resistance bridges, digital bridges, high-resistance meters, etc.

The resistors adopt fully sealed, light-pressure precision instrument switches that do not require cleaning, have small contact resistance and variation, and a long service life. The resistance elements are made of high-quality alloy wire wound and undergo strict process treatment and long-term aging, endowing the resistors with high accuracy and good stability.
