A4400 VA4 Pro II
The Fastest 4-Channel Vibration Analyzer
Do you want to measure 4 AC (vibrations) channels synchronously? Yes, with A4400 VA4 Pro II you can do that and you don’t even need any input adapter!
The A4400 VA4 Pro II is a unique analyzer for machinery vibration diagnostics which will fulfill all your vibration diagnostics needs. The A4400 VA4 Pro II 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 II is designed for engineers, technicians and researchers dealing with machinery and structural diagnostics as well as dynamic balancing of rotating machinery.
