Where to buy air sampling probe?

[Wes <vanpelt@ios.com>]

Hi Radsafers,

I wonder if anyone knows of a commercial source for air sampling probes.  Let me explain further.  What I am looking for is a simple pipe which permanently goes into a stack or duct which will draw a continuous isokinetic air sample from the duct.  This is not much more than a pipe with a 90 degree bend and a flange or other mounting bracket.  They would have to come in a range of inner diameters so that isokinetic flow could be reached within the desired sample air flow range.

I know that in a big institution you can just ask "the shop" to make one.  But small companies do not have a shop.  Are there commercial metal shops which could make these.  (I have had trouble finding one which can work with stainless steel tubing.)

Thanks in advance for any leads.
