Cobra V Probe

Maximize your results with Lonkar’s Cobra V Probe – a user-friendly, technologically advanced downhole probe providing maximum data integrity and extended real-time data logging capabilities.

  • High-speed CMOS surface mount technology.
  • 4Mb Flash Memory downhole data storage allows for the retrieval of 500,000 time/pressure/temperature samples, expandable to 1,000,000 samples upon request.
  • Multiple start and multiple record capability facilitates the logging of several wells before data downloading is necessary.
  • Extended battery pack will permit six months of well data logging.
  • Real-time mode provides for instantaneous probe data display in engineering units, making probe testing and calibration more effective and efficient.
  • On-board real-time clock ensures every data sample is date and time stamped.
  • Variable speed sampling rates with user-selected trigger values ranging from two samples per second to one sample per hour. Burst size (1-9) is user-selectable at all speeds and provides greater data integrity.
  • Pressure Trigger Mode allows preset changes in pressure to activate fast sampling rates.
  • 15 Data Acquisition Periods (DAPs) are individually user programmable.
  • Quartzdyne transducer provides superior probe performance when operating in period-counting mode.
  • “Point and click” user-friendly data processing and display facilitates quick and easy data analysis. Data retrieval and probe programming is possible with both DOS and Windows operating systems and all programming information is stored in the EEPROM microprocessor. The processed data structure is compatible with most well evaluation software.
