Ayrton & Perry Voltmeter, 1883-1890
Add to SetSummary
Companies that generated and distributed electrical power in the late 1800s needed equipment to monitor and measure output. Apparatus used in scientific laboratories proved insufficient. Electrical engineers needed robust, rugged, and portable instruments that they could read quickly without performing complex calculations. William Ayrton and John Perry developed this direct reading voltmeter among other measuring instruments for the new industry.
