Amptec 620UK Intrinsically Safe Igniter Tester Ohmmeter

AMPTEC 620UK Intrinsically Igniter Tester Ohmmeter

The AMPTEC 620UK & 620UK-V4 are Intrinsically Safe Igniter Testers, EEX designed for ultra-safe resistance testing on squibs, flares, bridge-wire, and other explosive devices. The 620UK’s Failsafe and Intrinsically Safe 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.

AMPTEC’s 620UK is a 2 measurement-wire ohmmeter requiring zeroing of the test lead’s resistance on the low ohmic ranges. Consequently, its running mate is the 620UK-V4 which features  automatic lead resistance compensation. Both models offer resistance measurement and testing of explosive or volatile devices.  Some of the ordinance type devices the 620UK and 620UK-V4  may be used on include: fuses, squibs, igniters, EBW, explosive bolts, rocket motor squibs, explosive bolts etc.
