3-Channel Vibration Analyzer, Data Collector and Many More

The A4300 VA3 Pro is the newest addition to our range of portable devices for vibration diagnostics. Signal inputs allows to connect two individual acceleration sensors or one Triaxial sensor. Input for speed probe is always ready to trigger your all three channel measurements simultaneously!

IR temperature sensor (for bearing temperature measurement) and a LED stroboscope/torch are built-in and ready to go by one button press. The A4300 VA3?Pro is?designed for one-handed operation. With a?weight of just 780g and a battery life of more than 10 hours of continous operation, the unit is suitable for?long route measurements.

The A4300 VA3 Pro instrument can be configured according to your requirements by choosing optional modules.
