certainly you should be able to - the humidity is most important, and that is affected by temperature as that relates to condensation risk, but ideally also you need to have ventilation rate information or a model - or you will be identifying all 65% plus humidity areas in a building as being at risk, not just those with a lack of air changes or warm temperature..

I have a Extech IRT600 Daul Laser Infrared Thermometer with Humidity and Dew Point test meter. 
 Extech Instruments is a Flir company, the tester is now obsolete and I can&rsquo;t see what, if anything, they have replaced it with. It is literally point and test, with a screen displaying information and a traffic light green, amber and red indicator lamp above it. 
 The tester gives a quick and clear visual indication of where black mould may develop, particularly in corners of rooms and helps to explain black mould issues to people.

 It is part of the Domestic Ventilation testing kit I have, along with an air flow anemometer and moisture meter. 
 I have a couple of books, but I can only find one at the moment, the Dri-Eaz Restorative Drying manual, a good general reference, but over sixty quid second hand on Amazon, reference books are expensive!

 Best of all, one of my neighbours was the National Franchise Manager for an insurance remediation company and he was a great source of information, if he didn&rsquo;t know the answer to questions about drying buildings out after floods and leaks, and preventing black mould developing in the meantime, he knew someone who did, but unfortunately he has now retired

I didn&rsquo;t find anything with a worked example yesterday evening, but looking online I see that Knauf now have an Online Condensation Risk Calculator.
