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.
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.
Temperature of Operation from -20 to 50℃
Relative Humidity 0~95%
Radio-frequency 10 mW/cm2 up to 4 GHz
affects meter viewing < 10%
Magnetic 200 Gauss ± 5% effect cm
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.
