The kVp meter and exposure timer measures the peak x-ray accelerating voltage from tungsten x-ray generators. To measure peak kV the user simply places the instrument in the beam and takes an x-ray. In addition to measuring kVp, the unit also measures the exposure time and displays the x-ray waveform type. The kVp Meter can be used on radiographic, fluoroscopic and dental x-rays. There is a high resolution mode which is used for measurements on older x-rays and x-rays with slow rise times.The kVp Meter has a large display which is readable from outside the x-ray room.
