Introduction
1.1 Product Description
The Model 07-479 Dental kVp Meter is designed to measure the effective peak potential applied to dental
type x-ray tubes. The measurement is made without direct connection to the x-ray unit being tested. The
kVp Meter is a battery powered, self-contained instrument designed for portable use.
The kVp meter uses two differentially filtered detectors whose ratio of integrated outputs is calibrated over
the range of 45 to 90 kVp. Measurement results are presented on an easy to read 3 ½ digit liquid Crystal
Display. Status is indicated by decimal point positioning on the readout. Low battery condition is indicated
by LO BAT displayed on the readout.
