X-RAY COMPLIANCE TEST METER

Model # TBM-XR w/Built-in Detector
Model # TBM-EXR w/ Separable Probe

FEATURES: X-RAY MACHINES, TV, and MONITORS LUGGAGE and PEOPLE SCANNERS ONE HAND OPERATION - Both Models DIGITAL READOUT: 6 digit-rate, 6 digits integrate SMALL LIGHTWEIGHT: 2-3 lbs SEES AXIALLY BELOW 15 KeV GAMMA OR X-RAYS FLAT RATE RESPONSE - AIR EQUIVALENT SCINTILLATOR - 15 KeV - 500 KeV WIDE RANGE APPLICATION: Model TBM-XR and TBM-EXR allow rapid, accurate compliance testing of a wide variety of X-Ray machines, TV's and computer monitors, luggage and people x-ray scanners. Protects the health and safety of airport and shipping personnel while they protect the public. The TBM-XR and TBM-EXR are now smaller and lighter. Based on newest, more stable, essentially drift-free electrometer technology. DESCRIPTION: The TBM-XR and TBM-EXR consist of an air-equivalent organic scintillation probe 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 0.01 mR/h to 100.00 mR/h in one range. Dose range is 0.01 mR to 10 R.

Model # TBM-EXR w/ Separable Probe

SPECIFICATIONS (Continued):  

• Electrometer: Solid State MOSFET input.
• Electronics: Adj H. V. Supply, Pulse Shaper. A-D converter LCD drivers. Test and display functions.
• Pulse Duration and Content: With sufficient repetitions, TBM-XR and TBM-EXR can accurately integrate pulses of less than a microsecond duration and longer and including continuous emission. Pulse content of 0.5 nanoR are measurable with sufficient repetition rate to give at least .01 mR/hr for at least 5 to 10 seconds.
• Environment:
      Temperature of Operation from -20° to 50° C
      Relative Humidity 0 - 95%
      Radio-frequency 10 mW/cm² up to 4 GHz affects meter viewing < ± 10%
      Magnetic 200 Gauss ± 5% effect
      Geotropism < ± 2% effect
• Response Time: 2-3 seconds for rate and for integrate.
• Time to Zero: If count-rate goes to zero, the digital display will hold the old count for 12 seconds before displaying "0.0."
• Batteries: Front panel battery test is provided.
  6 ea. (AA) NEDA 15A - over 100 hrs of operation.
