High Temperature NaI (Tl) Scintillator

In petroleum logging, NaI(TI) scintillator works underground, and must withstand high temperature above 150°C, certain shock and vibration. The high-temperature NaI(TI) serials adopt polycrystals forged under high temperature, unique high-temperature resistant materials and reliable packaging technology. The working temperature range is -30°C~ +175°C. It has excellent mechanical shock resistance, temperature shock resistance and long lifetime. The while drilling serials can work at 175°C and 30g strong vibration. Products are mainly used in nuclear logging.
