That is quite interesting and great DD. My interest in this is that I am a property's inspector by trade and also a member of the human race. When I inspect a house people are interested in air quality and water quality as well as the foundation. We look at different things but usually issues are something which can't be seen. Some times you can smell stuff or see mold and we do test and send things off to the lab. The same things happen with food. Lucky for all of us that life threatening pathogens are not that common. I spoke with Jeffrey as a potential customer for the MIT 1000 and newer generation machines wanting to expand current business. He said the machines work, once the certifications for the big 3 are in, people will have more faith in the system. He also said they will expand the library to customers needs. Weather for our security or the life sustaining things we come in contact with on a daily basis this is an awesome direction this is all headed, IMHO .
