The Model TBM-IC-Pulse-X is useful in applications where pulsed nano-second X-rays are present. The portable ion chamber is based on stable electrometer technology. 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 measures unusually low energies and short pulses. A dangerous situation could occur if these energies go undetected.


The Unit features a 5 cm diameter air ion chamber fastened to a stable solid state MOSFET input electrometer with built in Analog to Digital converter. The unit displays in mR/h or total mR.
Rate range: 1 mR/h to 100 R/h in a single range.
Dose range: 0.001R - 100R in a single range. Other Ranges are also available.
