GENERAL INFORMATION:
The new 820 kVp / mAs Meter combines all the features of our kVp, along with an mA / mAs meter in one compact unit. The 820 is capable of measuring kVp, mA, mAs, and exposure time. The unit is self resetting, and automatically detects AC or DC x-ray currents, minimizing the possibility of inaccurate readings. With each mA reading, the unit stores and displays mA, mAs and exposure time. mA is sampled for a representative length of time and saved. This allows shorter exposure times minimizing xray exposure and wear and tear on the x-ray head. The Model 820 contains exactly the same kVp measurement circuit and capability as our Model 815. The mA / mAs function has been squeezed into the unit. The Model 820 is battery operated, user-friendly, and has a two year warranty. Applications include verification of peak x-ray voltage, constancy checks, calibration of x-rays, and quality assurance measurement of exposure time. The unit is also used for half value layer determination, troubleshooting and repair of x-rays, and quality control.
The cable supplied with the unit serves as a switch. When the cable is plugged into the unit, it is automatically configured for mA readings. When the cable is unplugged the Model 820 functions as a kVp meter.
The introduction of the Model 820 allows service personnel to carry one instrument rather than an mAs Meter and a kVp Meter.
