SCAL2 Handheld AE Calibrator
Designed and developed for the requirements of acoustic emission detector calibration. It can export various standard
parametric signals like amplitude, rise time, counts and duration. SCAL2 is suitable for calibration of availability of AE
detector, AE sensors and preamplifier before using them, and it is suitable for detecting the working condition of
acoustic wave (acoustic emission) detection system in a local environment. The design of SCAL2 is based on
