8540.89.00.60/Photomultiplier Tube R928/Germany

Photomultiplier Tube R928 from Germany

The Hamamatsu R928 is a head-on type photomultiplier tube featuring a semi-cylindrical photocathode that provides high sensitivity to low light levels. It amplifies photoelectrons through a series of dynodes to produce a measurable electrical signal, making it ideal for scintillation counting and spectroscopy. Classified under HTS 8540.89.00.60 as a light-sensing tube due to its photocathode design for detecting and amplifying faint light signals.

Import Tips

• Verify photocathode material and dynode configuration in technical specs to confirm classification as light-sensing tube under 8540.89

• Include manufacturer datasheets and end-use declarations to avoid misclassification as imaging tubes under 8529

• Ensure radiation shielding compliance if used in high-radiation environments, as these may trigger additional certifications
