ADASH A4400 VA4 Pro II (4 Channel) Vibration Analyzer and Data Collector
Overview
The ADASH A4400 VA4 Pro II is a 4-channel instrument for machinery vibration diagnostics, combining analysing, data collecting, and vibration signal recording in one portable unit. It is designed for engineers, technicians, and researchers working on machinery and structural diagnostics as well as dynamic balancing of rotating machinery.
The instrument includes modules for FFT analysis, data collection, signal recording, dynamic balancing, measurement of run-up and coast-down, acoustic measurement mode, and the Adash expert system for automatic machine fault detection.
Engineering & Design
The A4400 VA4 Pro II provides a large colour display for waveform, spectrum, and trend presentation, with four simultaneous measurement channels for complete machine condition assessment. The expert system automatically evaluates measured data and indicates potential machine faults, supporting less experienced users in diagnosis.
The dynamic balancing module guides the operator through single and multi-plane balancing of rotating machines, and the run-up and coast-down measurement modes capture resonance and critical speed behaviour for rotor and foundation analysis.

Condition monitoring programmes need capable instruments, and the ADASH A4400 VA4 Pro II vibration analyzer delivers, which is why Seven Star LLC supplies the ADASH A4400 VA4 Pro II for predictive maintenance projects.
The ADASH A4400 VA4 Pro II analyzer collects the vibration data of the rotating machinery with four simultaneous channels and the balancing function. The instrument is carried to the machine and the accelerometers are mounted on the bearing points with the magnets or the studs. The measured spectra are stored in the instrument memory and are transferred to the software for the diagnosis of the machine condition.
The A4400 VA4 Pro II is used for the balancing of the rotating machines with the single plane and the two plane procedure, and the trial weight is calculated by the instrument. The route mode guides the operator through the preconfigured measurement points of the machine. The recorded data are reviewed in the office software and the alarms are set according to the ISO vibration limits. The instrument is supplied with the accelerometer, the magnet and the cable set.
The A4400 VA4 Pro II is supplied with the route management software and the measurement templates for the standard machine types. The instrument supports the order analysis and the resonance testing of the machine structure. The collected data are compared against the previous routes for the trend of the vibration level.
The instrument is supplied in the carrying case with the charger and the software licence, and the data are transferred over the USB connection to the analysis station.
Why Seven Star LLC
Seven Star LLC supplies the ADASH A4400 VA4 Pro II vibration analyzer for condition monitoring projects across the Gulf, with verified specifications and technical support. Our team assists with instrument selection, training needs, and measurement programme planning.
We support predictive maintenance programmes in oil and gas, power, and industrial plants throughout the GCC.
Diagnostics Performance
The four simultaneous channels allow complete machine assessment in a single measurement pass, and the FFT analysis with the Adash expert system supports both experienced diagnosticians and newer users. The dynamic balancing module extends the instrument’s value to on-site rotor balancing work.
Run-up and coast-down measurements capture the resonance behaviour of machines and foundations, and the acoustic mode adds a further diagnostic dimension for bearing and leakage analysis.
