draught detectors

[RAS]

Anyone know where I can purchase a "draught detector"

We used to use them in health and safety checks.
They are a small rubber bulb, hand held, that are filled with talcum powder. A quick squeese and a puff off talcum powder spreads out .and shows any air movement in the area.
Thanks for reading

I know it's not the same but if you cannot locate puffer, try this one:-
