Founded in 1928, Martindale Electric Ltd has maintained a reputation for manufacturing long lasting and hard wearing test instruments. Famous for the Classic Check Plug socket tester, Martindale has recently launched the E-Ze check, a socket tester with built in non trip earth loop impedance indication. The innovative Fuse Finder takes away the hassle of needing two people to perform a one man job, thus saving time and preventing costly mistakes when identifying which fuse or breaker to pull.
