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.
  • The datalogger can be employed outdoor and indoor.
  • The 10-bit resolution guarantees a resolution 4 times higher than 8-bit products commercialised by competition, making the use of F880 ideal for detailed acquisition.
What’s New with Geosignal F880
  • The difference between F880 and other dataloggers is simple:
  • Total electrical insulation between the sensors and the datalogger core.
  • Total electrical insulation between the channels.
  • 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.
  • Palm crossed adapter.
    Accessories are sold separately
