620UK | Intrinsically Safe Explosive Safety Ohmmeter

The AMPTEC 620UK Ohmmeter is a portable EEX digital igniter tester designed for ultra-safe resistance testing on squibs, flares, bridge-wire, and other explosive devices. The 620UK’s failsafe design allows it to comply with the EU ATEX Directive, the Intrinsic Safety Standard EEX-9B-IIC-T4, and USA MIL. STD. 810F, as well as many other international defense standards. Additionally, this product is available in a 4-wire version, known as the 620UK-V4 ohmmeter.
