Simpson Electric has been defining the industry of test instruments since 1927. A company defined by their innovations, Simpson Electric pioneers in areas like the first to use non-shatter glass in instruments, the introduction of commercially-practical core meter movement and the first to put a zero adjust on lower-cost high-grade instruments.
It was the 260 Volt-Ohm-Milliammeter that defined Simpson as a company with quality products. Their products continue to uphold that reputation crucial in industries using digital or analog panel meters and other test instrumentation products.
