Multiple channel vibration analyzer is usually defined as a high-end handheld product to be developed because it is an important part of your predictive field diagnostic system, MS502 is that kind of product.

It performing condition monitoring data collection,analysis, and root cause correction in rotating equipment applications such as motors, fans, pumps, gear boxes and others, not only for common defection analysis but also often used to deal with complicated critical issue which is corresponding to mechanical structure, basement structure, material rigidity and production process control rationality so on.

Two simultaneous vibration channel as well one RPM channel make MS502 to implement comprehensive measurement capability, more dedicated analysis functions such as 2 plane dynamic balancing, orbit plot, cross-channel correlation and phase, long period measuring, also ease of use make it a powerful condition monitoring tool.
