Applications:
  • The datalogger F880 has been designed for monitoring of pipelines or other large structures subject to strong surges.
  • Monitoring of sensors placed in deep wells.
  • Environmental monitoring plants like landslide monitoring plants.
  • Differential monitoring of sensors or sources having large voltage differences from one to the other.
  • Acquisition in remote areas.
  • Acquisition where a combination of large memory and low power is required.
  • Acquisition situations requiring flexibility and control of external devices or sensors by the datalogger.
  • Channels do not share a common ground and can even measure 150V one to the other.
  • Inputs protected by gas discharger preventing sparks to jump across electrical insulation.
Accessories
  • USB / RS232 cables for PC connection
    Accessories are sold separately
