This TBM-IC-Pulse-X is useful in non-destructive testing or various industrial and medical applications where pulsed nano-second X-rays are present. The portable ion chamber is based on stable, mostly drift-free electrometer technology. This model is the only portable ion chamber available, that will detect nanosecond pulsed x-rays. It will accurately measure the integrated Total Dose from pulsed x-ray machines over a wide range of pulse widths and repetition rates. This monitor also measures low energies and short pulses that other survey meters ignore. Workers could be at risk if these energies are undetected.
