kVP表kVp Meter ａnd Exposure Time Meter
The ECC 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 Capintec 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.
