The main, and significant difference between the Draeger device, and Lifeloc, is that Lifeloc's Spin Dx device gives a "Quantitative" measurement, whereas Draeger's device is simply Pass/Fail - Huge Difference.

An Important Note:
We need to differentiate a screening device from an evidentiary device.
In a screening device, analytical results are merely qualitatively identified as, in the case of the Dräger
5000 - POSITIVE or NEGATIVE (present or not present to a sufficient amount or, as in the case of breath
alcohol screening devices - Pass, Warn, or Fail).
A device is considered qualitative because no amount, concentration or quantity is measured – it
merely detects the presence of a specific substance in the test sample.
In a more complex evidentiary or quantitative device, the amount of the thing being measured is also
displayed (i.e, - 0.05 grams per 100mL, or 13 nanograms per millilitre, etc.). This degree of
sophistication would require substantially more calibration and control for reliable testing.
By identifying the Dräger 5000 as a screening device, Dräger is signifying the inherent limitations of the device, and that limitation should be respected as we examine its performance characteristics.
