|Series 8700 Pulse Counter/Exposure Time Meters.|
The Model 8700 X-Ray Pulse Counter/ Exposure Time Meter is used to measure the time or duration of radiation output
produced by a wide variety of x-ray generators. The x-ray sensor in the 8700 allows direct measurement of exposure from
the x-ray head. Pulses produced by half-wave and full-wave x-ray are measured as 60 or 120 pulses per second. For DC,
capacitor discharge and 3-phase x-ray, the 8700 measures the exposure time in milliseconds.|
When testing x-ray timers and controls, the time of relay contact can be measured using the AC input feature.
The Model 8700 is "self-resetting". There is no need to reset the instrument after each reading. The reading is stored after each exposure, holding until the next exposure.
The advanced circiutry in the 8700 provides the following improvements over competitors:
- Increased sensitivity allows use with lower power x-rays
- Wider dynamic range allows use with higher power x-rays
- Measurement ends at 70% of peak value eliminating inaccuracy due to slow tail.
