«Diogen-48/32» two - regime seismograph (New)

Powerful yet portable - all you need in one case


The «Diogen-48/32» can be applied as one of seismic modules of system and it`s successfully used for refraction or reflection, downhole or VSP, earthquake monitoring.

Features

  • Universal seismograph: engineering researches, depth to bedrock, hydrologic investigations
  • Reflection
  • Refraction
  • Sub-bottom profiling with use of special pulse sources
  • Earthquake monitoring synchronizes with GPS clock
  • Interface - WiFi (notebook, PC)
  • Testing bad geophones, cables (built-in)
  • Built-in test oscillator
  • The program analyzer of a spectrum of the written down signals
