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

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.
SPECIFICATIONS:

• Detector: Air equivalent plastic scintillator.
• Window: Light-tight 0.9 mg/cm² Mylar laminate. 10 sq cm area. 36 mm (1.4") dia.
• Readout: LCD 8 digits
• Indicator Light: Green LED 10 pulses/min per mR/h.
  Red LED Over-range Indicator.
• Range:
      Rate 6 digits 0.01 mR/h to 100 mR/h in one range.
      Integrate 6 digits 0.01 mR to 9.9R.
• Photon Energy Range: 15 KeV~ 500 KeV ± 20%
• High Voltage: Fully user adjustable (internal pot).
• X-Ray Rep Rate: Use either rate or integrate mode for pulses with repetition rate of less than 1.5 sec.
  Use Integrate Mode for greater than 1.5 sec.

• 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℃
      Relative Humidity 0~95%
      Radio-frequency 10 mW/cm² up to 4 GHz affects meter viewing < 10%
