Derived from the original USAF’s AMPTEC 620UK based Bonding Milli-Ohmmeter, the UL 913 Intrinsically Safe AMPTEC 620LK Safety Bonding Milli-Ohmmeter measures lower bond resistance levels with greater accuracy. It measures very low resistance bonds that are less than 1 milli-ohm (on the Lockheed Martin F-35 Joint Strike Fighter). The high resolution version AMPTEC 620LK Bonding Milli-Ohmmeter has wider (lower & higher) dynamic ranges, while the standard version 620LK offers lower cost with good measurement accuracy for +90% of the common bonds.
