Main features:
  • Fast detection of gamma anomalies
  • High sensitivity of measurements
  • Portability and ease of use
  • Arrow and sound indication
  • Integration time adjustment

Borehole scintillation radiometer SRP-20 is the most advanced version of previously popular radiometers SRP-97K and SRP-68-02/03 and their analogue in terms of functional use and application domain. SRP-20, alike previous versions, is a scintillation radiometer and is designed to search for radioactive ores using gamma radiation logging. Due to the presence of Bluetooth and USB interfaces, data can be transferred to a PC in real time. It is also possible to increase the time integration window in order to obtain stable data on anomalies that are close to background values.

Package contents:
  • Borehole Detection Unit
  • Measuring console
  • Battery (built-in)
  • Charger
  • Headphones Koss Porta Pro
  • Control source (Co-60) in a container
  • Rugged Case
  • Reel with a slip ring
  • Well logging rod feeder system with rods (optionally)

Borehole scintillation radiometer SRP-20 can be supplied with a well logging rod feeder device and rods that provide supplying of detection unit into horizontal, inclined and vertical wells.
