| Wide Range Digital kVp Meters. |
 | 
IntroductionWhether you choose the Wide-Range, Mammographic, or the Dental Digital kVp Meter, you will get quick and accurate measurements of your diagnostic x-ray generator tube potential. These instruments need no connection to the x-ray generator. Applications These lightweight, rugged units are extremely easy to use: simply place on the x-ray table, with the detector facing the x-ray source. With the beam’s central ray centered on the detector, an exposure is made, and the reading appears immediately on the large, easy-to-read liquid crystal display. Unique features are provided to ensure maximum efficiency and accuracy. Readings remain on display until the next exposure is made, at which time the reading is automatically updated. Automatic display indicators tell you when adjustment of exposure factors or battery replacement is necessary. Neither remote-control cables nor time-consuming manual re-zeroing are needed. A BNC connector is provided for radiation waveform display on a storage oscilloscope.
