About Martindale Electric

Martindale Electric, founded in 1928, also owns the Edgcumbe Instruments Metrohm® products, as well as the John Drummond Engineers range of test lamps. We are a British owned company, based in Watford, just 5 minutes from junction 5 of the M1.

Our product range helps electricians and maintenance engineers carry out portable appliance testing, check fixed wiring for 17th Edition and Part P testing, safely prove dead, and measure everything from light and sound levels to microwave leakage and power consumption.

• The first ever socket tester.
• The first safety insulation tester.
• The first self proving non-contact voltage indicator.
• The first low cost fuse finder.
• The first non-trip, no battery, no test button, loop tester displaying PE, PN PFC & PSC
• The first handheld insulation tester with polarisation index.
• The first advanced socket tester, as defined by the Health and Safety Executive.
• The smallest and lightest handheld PAT Tester.
