 Controle de qualidade em Radiodiagnóstico
245 kV Meter (Medidor kV)
 
     Description: Accuracy and convenience in one small package. The very compact Gammex 245 simplifies the determination of actual kV for radiographic, fluoroscopic, and mammographic x-ray systems. This highly accurate meter can be used for a wide range of energies and will store up to ten readings. A remote LCD display makes fluoroscopic readings easy to obtain. The meter can also be connected to an oscilloscope to monitor waveforms.

Features:

  • Radiographic, Fluoroscopic, and Mammographic non-invasive measurement modes
  • Dual methods of kVp measurements available in a single radiographic or mammographic exposure:
    • (1) the average of kV peaks, (2) effective kVp
    • (2) effective kVp
  • Use of patented Quadcell detector and autogain circuitry for unparalled accuracy in kVp measurements over a wide range of measurement conditions: orientation, positioning, angulation, and x-ray intensity have little effect on measurement results
  • Measurements of kVp can be accurately performed over an x-ray intensity dynamic range of 5000:1 at any specific kV
  • Internal correction factors for mammographic target/filter combinations
  • Automatic resetting for each exposure
  • Large LCD display
  • Compact size that fits in your hand
