Thermal Chambers - Apertures

Apertures allow you to pass wiring and test instruments through the wall of the chamber while maintaining the internal temperatures. Apertures are the most popular option for Thermal Chambers. Apertures are made with a thermally resistent material, and when used in conjuction with the supplied foam plugs, minimal heat and cold is passed through the ports.  The least expensive apertures are round and are available in standard sizes from 1 1/4" to 4" (I.D.). Larger, smaller and custom sizes are available. Square, or rectangular apertures are also available. 

If you move test setups attached to wiring, hoses, etc. in and out of the chamber, the best option is often a "Notch" at the front door edge.  Notches allow test setups to be moved in and out of the chamber without detaching any connections. Click Here for more information on Cable Notches.
