okay, so with an e-perm or charcoal tests, you’re supposed to have 2 canisters roughly 6 inches or so apart. This would be a 48 hour test. Now with above type of monitor, do i need to run it for 96 hours and check it at the 48 hr mark? or will that be okay at the 48 hr mark since it measures every hour.
Also, if i get the results on the spot and write the report, will that be considered a lab, technically?
