AmpSafe™ Ultrasound Leakage Tester


AmpSafe™ is specifically designed to test the electrical safety of all types of diagnostic ultrasound transducers, totally independent of the ultrasound machines on which they are typically used. Although AmpSafe™ can be used on virtually any type of ultrasound transducer, it is especially recommended in the testing of TEE (Transesophageal Echocardiography) transducers prior to each use; as recommended by many TEE ultrasound device manufacturers. AmpSafe™ tests the integrity of the outer insulation barrier of the transducer as well as the capacitive leakage currents that exist.

AmpSafe™ is the most advanced instrument of its kind on the market today and adds a new dimension to diagnostic ultrasound transducer electrical safety testing. With features and functionality that far surpass competitive products, like being able to transfer reports to a PC through a USB connection, AmpSafe™ is easy to set up and use.

Compatibility with other manufacturers’ adapters and Dual Conductivity Probes allows you to upgrade to the very latest technology platform, while safeguarding any prior investment in adapters and probes. AmpSafe™ is offered with a compact electrode designed to work with automated TEE disinfection stations.
AmpSafe™ is the first electrical leakage tester to incorporate a USB interface to connect to a PC for complete test report generation. The test report on AmpSafe™ will include detailed probe information, measurement values, tester identification, and the date to coincide with the Inter-societal Accreditation Commission guidelines.
