Sravani U 26. Maalis 2019 HI Paul, i do read your blog for many queries that arise during work course. they are very helpful. Thank you! :-) i have a question...during area or controlled chamber tempertaure mapping studies. is it a right practice to determine hot and cold zones during requalification (every year) temperature mapping for placing a continous monitoring probe? what if these hot/cold spots change every year? if the chamber already has more than one monitoring inbuilt sensor installed inside...periodic requalification is required?! Vastaa
