601ES | Weather Resistant Safety Digital Multimeter

The AMPTEC 601ES Digital Multimeter is used to measure stray voltage and current in harsh weather environments under NSN # 6625-01-619-8417. Additionally, all internal circuits are conformal coated, it contains an internal all-metal Faraday cage, and has a built-in self-test to ensure ultimate integrity of measurement. The 601ES DMM is approved by the NASA/WFF Safety Office for compliance with the WFF Range Safety Manual (RSM) and USAF’s Space Wing (AFSPC), proving its intelligent design is ultra-safe.
