EKOPHYSIKA-110A-HF

New generation of multichannel sound and vibration analyzers.

Ekophysika-110A-HF is a four-channel advanced measurement systems. It meets requirements of class 1 sound level meter, human-vibration meter, 1/n octave band analyzer. It can measure signal levels for the frequency range of  up to 400 kHz, and operate as a 4-channel digital data recorder.   

Functions
  • Number of channels: 1-4
  • Direct connection of condenser microphones, IEPE transducers, EF and MF antennas (P6-71/P6-70)
  • Class 1 sound level meter (GOST 17187-2010, IEC 61672-1)
  • Ultrasound measurement (up to 40 kHz or 100 kHz, depending on the frequency range of the microphone)
  • Infrasound measurement
  • Whole-Body and Hand-arm vibration measurement (GOST ISO 8041)
  • Simultaneous measurement of sound levels and three components of weighted acceleration (human vibration)
  • FFT analyzer, narrow band analyzer (selective voltmeter, up to 500 kHz)
  • Autostorage of measured data and/or signal digital time waveforms to the instrument memory
  • Real time data transfer to external devices, remote control of the instrument
Features
  • Sensor Manager handles the sensor catalog, calibration settings
  • Extended measurement range for whole body and hand-arm vibration
  • Graphic time-history
  • Multi-step Backerasing
  • Acoustic Calculator
  • Post-processing of auto-saved files
  • Repeated Measurement combines data of several manual measurements in a common file
  • Text logbook of measurements
