The AMPTEC 620A-4R Igniter Tester was designed to be a ruggedized version of its predecessor, the 620A-4 meter. The 620A-4R contains the same inner circuitry as the ultra-safe 620A-4, with the added bonus of protection in harsh environments, an internal Faraday cage for noise immunity, and a wide-viewing angled display. This product is widely used by both military programs and commercial clients who require a weather-proof failsafe igniter tester.
