kV Meter
GAMMEX 245 |
|
|
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 of the Gammex 245:
• Radiographic, Fluoroscopic, and Mammographic noninvasive measurement modes
• Dual methods of kVp measurements available in a single radiographic or mammographic exposure:
(1) the average of kV peaks, (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
