Voltage calibrator SCAL2

frequencysignalsound level

SCAL2 Handheld AE Calibrator are 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 ‘JJF1505-2015 Calibration Specification for Acoustic Emission Instrumentation’. It also can be used as a standard signal generator.
