Whenever a fast, sensitive ion chamber instrument is needed, the TBM-IC-MARK V is the latest in a series. The TBM-IC-MARK V ion chambers are now smaller and lighter. Based on newest more stable, essentially drift-free electrometer technology.
The TBM-IC-MARK V consists of a 2.5″ dia x 3.5″ long air ion chamber coupled to a stable solid state MOSFET input electrometer with built in A to D converter to read out directly in mR/h or mR. Rate range is 0.1 mR/h to 9.999 R/h in a single range. Dose range is 0.01mR – 99.9R in a single range. 180 mg/cm graphite lined methacrylate walls accurate “air equivalence.” Thin (0.5 mg/cm ) Mylar window allows high sensitivity readings for alpha and for low energy beta such as C14 in addition to higher energy Betas, Gammas and X-rays.
