ECC Digital X-ray Pulse Counter 8700
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.
New and Improved!
We have recently made significant changes to the design of our Model 8700 to improve the function and accuracy. No changes were made regarding the actual operation, so the units work the same as existing models.
However, the following performance improvements were made:
Wider Range
Increased sensitivity allows use with lower power x-rays
Wider dynamic range allows use with higher power x-rays
More accuracy on DC/Multiphase high power x-rays
Measurement ends at 70% of peak value eliminating inaccuracy due to slow tail.
New circuitry saves production time and parts cost, allowing us to keep our competitive prices.
Low power circuitry improves battery life.
