Overview
The rotary resistance box is a commonly used instrument in all laboratories, suitable for electrical measurement and other experimental use in schools, factories, and research institutions. device
Product Details
Rotating resistance boxPurpose:
By switching, known resistance values for each level can be obtained. The ZX74 type DC resistor is a multi value DC resistor composed of six ten input reading disks connected in series. The switch used in the resistor is sealed, does not require cleaning, has low contact pressure, long service life, and small variation. The support is made of high insulation engineering plastic, and the overall insulation resistance of the machine is high. The resistance elements are all made of high-quality enameled manganese copper alloy wire wound without inductance, and undergo strict process treatment to have high stability.
feature
The resistance box support has a potential lead out terminal that can be verified according to the components. The contact ring, contact piece, and brush in the switch are all tightly pressed with micro springs. Therefore, after use, the contact resistance deteriorates less. The support is made of high insulation polystyrene material plastic, which has good insulation performance
