AMPTEC 620UK-V4 Intrinsically Safe Igniter Tester Ohmmeter  

The AMPTEC 620UK-V4 Ohmmeters is a portable EEX Intrinsically Safe Digital Igniter Tester designed for ultra-safe resistance testing on squibs, flares, bridge-wire, and other explosive devices. The 620UK-V4’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-V4 is a 4-wire Kelvin configured Ohmmeter which automatically compensates both for lead wire and contact resistance. This is most significant on the lower Ohmic ranges.  The Amptec620UK-V-4 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 ordinance devices including: fuses, squibs, igniters, EBW, explosive bolts, rocket motor squibs, explosive bolts etc.
