US-454A Multi-Frequency Eddy Current Instrument


The new US-454A brings the most innovative multi-frequency eddy current technology to the marketplace. This instrument has transformed eddy current testing by offering single and multi-frequency inspection; frequency mixing capabilities; unprecedented signal-to-noise ratio; USB and Ethernet connectivity; data storage capabilities; and superior digital strip chart data collection.

Built on the rugged US-454 architecture, the US-454A serves many applications in the field or the laboratory—any applications that demand highlevel, accurate, and flexible eddy current testing. This instrument is also uniquely suited for conductivity and thickness measurement. The US-454Aʼs unprecedented signal-to-noise ratio and filtering capabilities are ideal for specialty applications that are outside the scope of what eddy current inspection equipment typically can provide. The US-454A can be configured to 1, 2, 3, or 4 frequencies, depending on requirements. Special mixing and filtering capabilities can meet the needs of numerous specialty applications.
