620LM | Failsafe Igniter Tester with Diode Test Capability
September 4, 2015620ES | Mid-Range Digital Failsafe Ohmmeter
The AMPTEC 620ES failsafe ohmmeter was specifically designed for ultra-safe testing on squibs, flares, bridge-wire, and other explosive devices. The 620ES meets mid-range resistance requirements and offers a fail-safe current limiting resistor network circuitry to insure test currents cannot exceed 8 mA. Capable of making highly accurate resistance measurements from 2 Ω to 200 KΩ, this ohmmeter has a proven track record of durability: with 20+ year old units still being used in the field today. This product was derived from the USAF Non-Nuclear Munitions Safety Board approved AMPTEC 620A-4 meter – thus creating a product line that is the industry standard in igniter testing.
