Joyridin: My theory is based upon over 24 years of building rockets for NASA, the DOD, the MDA and commercial industry. The latest is a small vehicle called Antares - goes to the space station sometimes. And no, this device is not used by us, our suppliers, or our customers since it is not a Mil Spec allowed technique. At 3% accuracy, a user may think the composition is accurate, and an answer is produced, but the answer may well be wrong. The sellers do state on their website that this is used in Aerospace though, and we all know it has to be true because its on the internet. I have confidence you are using this device within its intended parameters and wish you the best, but I have looked at the specs and again wouldn't (and don't) base million dollar decisions on it.
