RH802 Spectrum analyzer is portable but powerful vibration spectrum analyzer developed by very experienced expert and mechanical maintenance expert. Offers some characteristics function, such as long time domain waveform, XPM,run-up/down testing characteristics analysis and on site dynamic balance measurement, It is an ideal instruments specialize in doing equipment faults precision diagnosis and single or double plane dynamic balance measurement.



  • The large LCD screen, simple flow chart, compact and light weight, more convenient operation.
  •  Huge storage capacity, can meet high-capacity data acquirement.
  • Wide analysis frequency (0~40KHz), high spectrum resolution ratio, can meet the requirement for precise and complex equipment (high-speed gear) analysis.
  •  Very flexible parameters configuration including high and low band pass filter, sampling length and sampling frequency, etc. Meet the requirement of data acquisition.
  •  Data acquisition base on scheduled or unscheduled are allowable, unscheduled data acquired can be store by sequence number or by measure point number.
  •  Versatile measurement and analysis system:
  • Acquiring vibration velocity, acceleration, displacement probes;
  • Measuring time domain waveform, spectrum, overall value and long time domain waveform
  • Measuring XPM, cross-power spectrum, phase difference spectrum, and measuring the phase difference between two measure points.
  • Hammering impact response test, measure the natural frequency.
  • Long time domain waveform similar to digital tape recorder, record as long as 2 Mb data, replace tape recorder. Transient data can be recorded, such as rolling mill complete rolling process, and equipment starting state.
  • Run up/down testing analyses, to track the vibration varies in starting and stopping.
  • Single or double plane on site dynamic balance, users can complete dynamic balance test comply with the tips;
  • Overall value, capture the entire changing process for equipment transient vibration, convenient to analyze the changing connecting between equipment vibration and technical parameter on site, the interval time can be set as needed.
