For anybody interested in checking if their disty is hot at home, this worked well for me.
I simply built a plexi-glass enclosure around the detector and inside I rigged a little stand for a cheap titanium nail. Ran a metal coat hanger through a small hole in the roof as a dabber and placed fat dabs on the pre heated nail. Sure there’s a less antiquated way to achieve the same end but it worked well for my purposes.
