Model XR-201/MSB X-Ray Timer
The Model XR-201/MSB Solid-State X-ray Timer is a versatile instrument used to determine the length of exposure produced by x-ray generators. Because of its simplicity, an operator can perform an accurate and reliable timing check in less than 15 seconds. Just aim the beam at the target symbol on The Model XR-201/MSB and make an exposure. It’s that easy!
This easy-to-use meter also:
* Counts the number of x-ray pulses produced by
half-wave and full-wave rectified x-ray machines
at a rate of 60 to 120 pulses per second respectively.
* Times the length of exposure in milliseconds where
a pulsing source of x-ray does not exist such as found
in three phase AC medical x-ray machines, capacitive
discharge x-ray machines and DC-operated dental
* Counts the number of AC line pulses (up to 125V AC)
via the input jacks located on the side of the meter.
