I would think a Google search could reveal sources for these items---
I found many references to volume and surface resistivity test equipment.
Same for heat stability ovens (I highly recommend the Metrastat continuous oven for PVC!)
Blue M is a good source for aging ovens---(forced circulating hot air).
