The dynamic range and thin profile of these chambers make them ideal for virtually all X-ray service applications
Additionally, the -60E(xtended) chamber's increased sensitivity at lower energies turns the chamber into a "Universal" detector, covering mammography through R&F and beyond.
The 8231 holder is recommended.
