Howdy Capriciouss!

Seems like for 27K U$D you could buy your own equipment to certify the product!

Been looking more at the diesel side of things the past few days. Quite interesting. One of the new laser smoke meters can be had for about $1100, which of course I do not have. I'll keep looking for cheaper. Would love to be able to afford to buy instead of make-- more time for testing.

Photometers with an accuracy of +/- 0.5% and a sampling rate of twice per second can be had for about a c-note. Choosing a light source (perhaps a skelkwank diode) is the next chore in designing a homebuilt diesel smoke opacity meter. A calibrated scale can be made with known density optical filters.

Not sure whether I should use a smoke chamber or not. If you do, you have to keep a temp of 100C to prevent condensation in the chamber.

Why would I go to the trouble of all this? Gandhi, one of my heroes, said that we should be the change we wish to see in the world. I told you I was a control freak.... and like I said before, my automotive technician daughter got me into this. I'm giving her something that she can use in her own business, which she wants to have instead of working for someone else.

Guess you better throw me in the watering trough for unicorns over in the unicorn corral. I'm sounding kind of new-agey here.
