4 Or 2 Channels Vibration Analyzer 1600 3200 6400 12800 Lines FFT
Spectrum
HUATEC HG-904A Four channel multi-functional instrument, features a
versatile input port that can connect to various types of sensors.
It utilizes advanced microelectronics, signal analysis, and fault
diagnosis technologies, integrating equipment condition monitoring
and fault diagnosis capabilities into a single unit.
The analyzer Instrument includes the function of four-channel
vibration data acquisition, which can complete vibration
measurement on-site and automatically store tens of thousands of
vibration feature values and spectra of measurement points. It can
also display one to four channels of waveforms and spectra
synchronously on-site. Additionally, It can serve as an imbalance
detector, completing single- and double-sided dynamic balance
verification on-site.
