Home | Products | Bonding Testing | 620LK-HR | High Resolution Bonding Ohmmeter

The AMPTEC 620LK-HR is the high resolution version of the 620LK. It is an affordable and highly accurate electrical bond tester. Additionally, the 620LK-HR has all the ranges of the standard 620LK, as well as both the lower 20 mΩ and higher 20 Ω ranges. Originally designed for Lockheed Martin, the 620LK product line comes from a long lineage of ultra-safe testing equipment that now occupies a more commercialized space.
