Description
Neutron Probe utilizes a He-3 thermal neutron detector. It measures Neutron porosity in counts per second, which can be directly related to the porosity of the formation. The probe has been carefully designed to maximize the detector sensitivity so that good results can be achieved with source strength of only 1 Curie. The source is carried in a specially designed shield and the probe itself is the source handling tool.
Operating Conditions：Uncased or Cased；Borehole Fluid：Water or Mud
Features & Benefits
1, Improve the sensitivity of the detector, guarantee the accuracy of the measurement results of stability.
2, Using weak source design, reduces the radiation dose using the people suffered.
3, Using two levels of source cans, convenient operation, further strengthen the protection.
