ZX25A DC resistance box (six sets of switches)It is a resistance measuring tool with variable resistance value. The switches used in resistors are sealed, do not require cleaning, have low contact pressure, long lifespan, and low voltage transformation.
1、Widely suitable for measurement and other experimental purposes in factories, schools, and research institutions.
2、Used for precise adjustment of resistors and known resistance values in DC circuits.
3、Can be used for whole machine calibration of portable DC single arm bridge and resistance thermometer, etc.
