Model 870
mA, mAs & Exposure Time Meter
The Model 870 is a solid-state, digital instrument designed to assess the performance of medical X-ray generators. This instrument measures and displays mA, mAs, and exposure time for each X-ray exposure and can be used to test dental, radiographic, and fluoroscopic X-ray units. This is a new state of the art instrument with many advanced features. For example, entering correction factors for different types of X-ray waveforms is not required since the Model 870 has the capability of automatically determining the type of X-rays being measured. In addition mA, mAs and exposure time are displayed and stored for each X-ray exposure further minimizing the number of X-ray exposures.
