Has anyone looked into getting a formaldehyde tester?

I know that we all can punch holes in the whole “ecig 10x formaldehyde” lie but Im really interested in doing my own research. I want to get one of these and run some tests myself. check the levels at my local vape shop where its hard to see the other side sometimes. lol. then go check Home Depot, a new car and so on. Anyone done this or have some thoughts???
