The Portable Wheatstone Bridge Apparatus is a device used in electrical engineering to measure resistance. It consists of a circuit with four resistive arms, two of which contain the unknown resistance being measured. The device can be calibrated for precision and is designed for portability. It can measure resistances ranging from a few ohms to several megohms, making it a useful tool for fieldwork and diagnosing electrical problems.

• The Portable Wheatstone Bridge Apparatus is a portable device that comes with a sensitive galvanometer, a dry battery, and a measuring range of 1.000Ω to 10.00MΩ.
• It has a range multiplier, carrying case and connecting leads for convenience.
• The device has an internal galvanometer but also provides the option of an external one with a terminal.
• The toggle switches are for internal or external battery and direct or shunted sensitivity of the galvanometer.
