Measures kVp, mA, mAs, Waveform & Exposure TimeECC Multifunction Meter, Electronic Control Concepts 820 & 820L
The 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 x-ray exposure and wear and tear on the x-ray head. 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.

Low Range Model 820L
The low range version of the kVp meter boasts the flexibility to provide precision at low kVp and low mA operation. The low range option is perfect for digital x-rays as well as dental and fluoroscopy machines, which typically operate at lower kV and mA settings. The low range 820L can measure kVp as low as 40 kV and has increased current sensitivity to operate dependably down to 5mA at 50 kV. The low range models are optimized at lower currents and operates up to 115 kV at 100 mA. Contact Supertech for more information and pricing.
