The PL600 is an eddy current instrument of the newest generation. It is characterized by a completely digital signal processing. The instrument provides several methods of signal excitation and signal analysis (classical eddy current testing, pulsed magnetizing, harmonic analysis). Based on a modular hardware platform and a customized software configuration all types of eddy current testing can be performed: crack detection, heat treatment, material mix-up and grinding burn testing.
