795M Entry to FFT Data Collector and Signal Analyzer (1-Channel)
The 795M is an economical portable single channel multi-function data collector and FFT spectrum analyzer. It is versatile for overall values measurement, bearing condition diagnostic, spectrum diagnosis and in-situ-multi-plane balancing of rotating machinery (up to 8 planes of correction, up to16 point to check vibration).
