CH448-03-00 (Counting while drilling)

CH448-03-00 scintillation detector (while drilling) is a high temperature resistant and vibration-resistant scintillation detector. It integrates high temperature vibration-resistant NaI (Tl)  crystal, high temperature PMT assembly and voltage divider circuit. The unique design ensures stable performance of the detector in high temperature vibration environment.

This product has the advantages of simple and convenient use, high reliability and not easy to damage, and is mainly used to measure formation natural gamma counting in oil logging environment.
