The Fastest 4-Channel Vibration Analyzer

Do you want to measure 4 AC (vibrations) channels and 4 DC (process values) channels synchronously? Yes, with A4400 VA4 Pro you can do that and you don’t even need any input adapter!

The A4400 VA4 Pro is a unique analyzer?for?machinery vibration diagnostics which will fulfill all your vibration diagnostics needs. The?A4400 VA4 Pro includes modules for?analysing, data collecting and vibration signal?recording. The device?is?enhanced by modules for?dynamic balancing, measurement of run?up and?coast?down, acoustic measurement?mode, ultrasound measurement, monitoring and?control of?lubrication process and listening to?the?vibration signal with?the stethoscope feature. The instrument is?equipped with?an?expert system developed by?Adash, which automatically detects machinery faults.

The A4400 VA4 Pro is designed for engineers, technicians and researchers dealing with?machinery and structural diagnostics as well as dynamic balancing of?rotating machinery.
