As a bond meter or bonding milli ohmmeter igniter tester the AMPTEC 620UKB or 620UK-B replaces the AVTRON or  AVTRON 101 bond meter and ICT bond micro 

ohmmeter, including the PPM or PPM instrumentation R1L-E2B or Valhalla Scientific 4314A. The AMPTEC or amptec research Eex Intrinsically safe low resistance meter can be a Low Resistance Ohm meter including NSN 6625-01-542-7487  Igniter Tester. In addition the Failsafe Ohmmeter, DLRO, squib tester, or AMPTEC 620A or valhalla 4314A or alpha the amptec dlro micro-ohmmeter. The amptech, or amptek EEX or Eex and  EEX Intrinsically safe EBW also ebw or eed tester can also be a ETL tester or EED or squib checker  continuity tester. AMPTEC 620A-4 or 620ES, 630ES, 620A4R replaces the  Alinco 101BFG,  4000ITS, 4314, ohmmeter, ohmeter , Failsafe Ohmmeter or DLRO or squib tester and explosive safety meter. AMPTEC 620A or 620A4R can replace the 620A-4R or 620ES igniter tester failsafe ohmmeter. In addition the Alinco or NSN 6625-99-833-7949, NSN 6625-01-460-1499, Test Fire Set, cage code 1CRL2.
