SENSITIVE INTEGRATING ION CHAMBER

Model # TBM-IC-AJI

FEATURES: SEES X-Ray PULSE DOWN TO 0.3 µR 0.0001 mR to 1.0 R/hr -TOTAL DOSE WIDE RANGE: 0.1 mR/HR to 1.0 R/hr- RATE DIGITAL READOUT: 8 digit-rate, 8 digits integrate DOSE RATE & TOTAL DOSE READ OUT LIGHTWEIGHT 28 oz. (870 grams) TBM PACKAGE FLAT RESPONSE - FREE AIR ION CHAMBER SEES BELOW 2 KEV GAMMA OR X-RAY SEES ALPHA, BETA, GAMMA, X-RAY APPLICATION: Whenever a fast, sensitive ion chamber instrument is needed, the TBM-IC-AJI is the latest in a series. The TBM-IC-AJI ion chambers are now lighter. Based on newest more stable, essentially drift-free electrometer technology.   DESCRIPTION: The TBM-IC-AJI consists of a 3.7'' dia x 6'' 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 0.0001mR - 1.0R in a single range. 180 mg/cm2 graphite lined methacrylate walls accurate ``air equivalence.'' Thin (0.5 mg/cm2) Mylar window allows high sensitivity readings for alpha and for low energy beta such as C14 in addition X-rays down to 2 KeV to higher energy Betas and Gammas.
