Electronic Control Concepts! All Purpose EXPOSURE METER that measures kVp, mA, mAs, Dose, HVL and Exposure Time.
  • Available in Low Range as well.

    The new Universal X-ray Instrument (UXI) is capable of measuring x-ray kVp, mA, mAs, Dose, HVL and exposure time. One exposure is needed for kVp, mA, mAs and dose. Three exposures are needed for an accurate HVL measurement. The built in HVL calculator is used to calculate HVL. Each UXI comes with a 7 inch (178 mm) Android tablet. With the programmable delay, the unit is capable of measuring kVp for exposure times as low as 16 milliseconds. This allows shorter exposure times minimizing xray exposure and wear and tear on the x-ray head. The kVp measurement circuit and control program have been greatly improved compared to our other instruments. Accurate kVp measurements can be made for a wider range of x-ray intensity with less dependancy on distance from the x-ray head.

    The UXI is connected via a 14 foot (4.3 meter) cable to the tablet.

    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.

    All units come with a Certificate of Calibration. Yearly calibration is suggested.

    The introduction of the UXI allows service personnel to carry one instrument rather than a Dose Meter, mAs Meter and a kVp Meter.

    In addition to combining several proven instruments into one device, significant improvements have been made in the circuitry to improve accuracy, ease of use and range. There is a graphing capability that shows the x-ray waveform for each exposure.

    NEW SOFTWARE Operating System:
    Improvements have been made in both the internal microcomputer program in the UXI front end and in the tablet to facilitate faster measurements and fewer x-ray exposures. There is no minimum exposure time requirement for mA / mAs measurement. The mA and mAs measurements are more accurate because we are measuring the current for the entire x-ray exposure.The minimum exposure time needed for kVp measurements has been reduced to 16 ms. This allows more flexibility when the x-ray is set up based on mAs rather than exposure time. This new feature virtually eliminates sources of error

  • when certain techniques result in short exposure times. The shorter exposure times also give you less wear and tear on x-ray equipment as well as less x-ray exposure to test personnel.

    This instrument is capable of measuring dose, kVp, mA, mAs and exposure time in one x-ray exposure. The HVL measurement requires three exposures, two with different thicknesses of Aluminum filtration.

    The program in the Android tablet can be upgraded as new features are added by connecting to internet. Users will be notified by email when upgrades are available.

    All UXI units come with a custom Carrying Case, that keeps your instrument and tablet safe and has room for cables and accessories.
