Typical mammographic and diagnostic kVp meters
Typical mammographic and diagnostic kVp meters

Calibration of non-invasive voltage measurement equipment (kV meters), traceable to standards of electrical potential.

Instruments are calibrated in X-ray fields produced using a constant potential high voltage generator.

Features

Mammographic kV meters:

  • Meters calibrated using a molybdenum-anode X-ray tube
  • Measurements available from 25 kV to 50 kV in 1 kV steps at maximum tube current ranging from 30 mA at 25 kV to 20 mA at 50 kV

Diagnostic kV meters:

  • Meters calibrated using a tungsten-anode tube
  • Measurements available from 40 kV to 150 kV in 5 kV steps

Availability

  • Calibrations are available throughout the year by arrangement
