Reach Ins Agree Vibration Compatible Chambers

Industrial-quality chambers for combination testing with vibration systems

For years AGREE chambers have been the workhorses of the environmental test chamber industry. Originally created to meet military test standards, their flexible design has made them suitable for a wide variety of applications. Fast temperature changes of 5 to 25°C/m. are possible, even with significant loads. The chambers have a removable floor, allowing integration with vibration test systems. Custom designs are common, allowing configuration to meet your exact requirements.

  • Special model EADX52 can interface with both vertical and horizontal vibration systems
  • ETL-listed electrical panel conforming to UL 508A


ESPEC custom chamber capabilities:

Nearly every Agree chamber we build is designed per the application. Here is a review of what is possible with a custom designed chamber from ESPEC. This video highlights automation and movement, both common in Agree-type applications with vibration systems.

  • Full-opening door with multi-pane heated window & interior light
  • Chamber floor designed to be changeable to accommodate different “floor plugs” for vibration systems. Standard floor plug provided is “solid” for non-vibration applications (other floors optional). Embedded perimeter heaters in floor plugs to avoid condensation and freeze-up, plus Teflon glides in floor slot make floor replacement very easy.
  • One 4" cable port with flexible plug centered in the left hand wall (additional ports optional)
