Hand-held AE Calibrator

Brief instruction


SCAL2 Handheld Acoustic Emission Calibrator Series are designed and developed for the requirements of acquisition host calibration of acoustic emission detector, which is based onJJF1505-2015 Calibration Specification for  Acoustic Emission Instrumentation, and also can be used as a sample standard signal emission, in order to export standard acoustic emission signal waves, mainly used for calibration of the AE instruments. Scal2 series can export various standard parametric signals, can be used on calibrating AE indicators like amplituderise timering-down count and times of duration. Scale 2 series are applicable for calibration of AE instrument before useusability of AE sensors and AE preamplifier, and is especially applicable for distinguishing and testing the working condition of the AE systems quickly once on the testing environment site.
