| WHEATSTONE BRIDGE, SLIDE WIRE FORM
(0688) |
| For determination of unknown resistances or comparison of resistances. This bridge has broad, heavily plated metal strips mounted on a sturdy anodized aluminium channel section base. Terminals with 4mm sockets are provided to reduce unwanted resistance to a minimum and the gaps are closed by removable plated brass strips, which are held in position by the terminals. The 24SWG bare constantan wire is stretched along the top of a meter scale graduated in millimeters and figured every centimeter. The ends of the wire are securely clamped to the terminating strips to reduce end errors to the negligible level. Features a double-end slider type knife edge for quick, easy and accurate determination of null point. Wire easily replaceable if damaged or broken. |
