Was there topic category to buy/sell equipment? (and if so where did it go?)
I am looking for someone wanting to sell Airthings Corentium Pro devices to add to our inventory.
ALSO, I have 14 E-Perm boxes in good condition with S Chambers, two Rad-Elec monitoring devices, and one electret reader to sell. The s chambers have electrets but I do not know the current levels.
Thank you, That is what I was looking for but was not seeing it.
