What is the best way to verify service temperture and humidity 48hr before rh testing? If you use a data loger where should it be placed?
I typically meet the client before hand to check out the site. I leave a thermhygrometer that records the past couple days. Just a cheapy one from radio shack. But then I don't do wide open commercial stuff either.
I think the best placement is right on the slab.
I look around and ask around. Because my work extends across state lines, I can't be there 48 hours ahead of time usually, but I can see if the building is enclosed, HVAC on or not, windows open etc.
