During World War II, the USS Pampanito completed six patrols, during which she sank six Imperial Japanese ships and damaged four others. The USS Pampanito is now a National Historic Landmark, preserved as a memorial and museum ship at Fisherman’s Wharf in San Francisco. As part of preservation efforts, the ship undergoes on-going maintenance as ships are the only museum artifacts that are regularly stored in a corrosive environment (saltwater).


Richard Pekelney, a member of San Francisco’s Maritime National Park Association, recently had a need for a product that could monitor and identify electrical issues on the USS Pampanito. Bender was delighted to assist by donating several Insulation Monitoring Devices from the ISOMETER® Series, which are specifically designed for marine and naval applications. The Bender iso685W-D-P was the perfect fit for the USS Pampanito as these devices can monitor, annunciate and locate insulation failure. The iso685W-D-P is intended for highly-corrosive environments and can withstand high levels of humidity, vibration, and other environmental conditions found on naval applications.
