The TBM-IC-PULSE useful in non-destructive testing or other industrial or medical applications where pulsed x-rays are
used. These portable ion chambers are based on newest more stable, drift-free electrometer technology. The TBM-IC-PULSE consists of a 2 inch diamter air ion chamber coupled to a stable solid state MOSFET input electrometer with built in A to D converter to display directly in mR/h
or total mR. Rate range is 0.01 R/h to 100 R/h in a single range. Dose range is 0.001R - 100R in a single range. Other Ranges are available.

The TBM-IC-PULSE will accurately measure the integrated Total Dose from pulsed x-ray machines over a wide range of pulse widths and repetition rates. This monitor measures low energies and short pulses that other survey meters ignore to the detriment of worker health.
