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

In addition, the P-300 touch-screen controller makes running an ESPEC environmental test chamber a breeze. The full-color, touch-screen interface is remarkably easy to use and understand. The P-300 Touch Screen Controller can be managed remotely via our new Ethernet/LAN-based Web Controller, serial port, or GP-IB/LabView.

ESPEC custom chamber capabilities:

Nearly every Agree chamber we build is designed per the application. ESPEC can build custom sizes, automation, and movement needed for applications with or without vibration systems.

New P-300 controller with USB

The exclusive ESPEC P-300 controller has USB and Ethernet features to make programming and data collection easier than before. The user interface uses tabs for faster access to any screen. Standard USB and optional Web Controller/Ethernet interfaces make programming and data acquisition much simpler. In addition, improved algorithms make operation faster and smoother.

DEMO: See how easy the P-300 is

USB port for upload/download of test profiles and test data

  • Test programs can uploaded or downloaded from the P-300 via USB thumb drive.
  • Create, edit, and store programs on a PC using the included Pattern Manager Lite software.
  • Accurate, repeatable testing by uploading the same program to multiple chambers.
  • Create your own back-up archive of programs, and get additional profiles from ESPEC's library.
  • Retrieve and download test operation data via USB thumb drive. Data timeframe is selectable.
  • For integrity, viewing test data on a PC and exporting to Excel requires included Pattern Manager Lite software.

Energy-saving operation

Invisible to the end user, the P-300 uses advanced cooling control via an electronic expansion valve, saving energy and improving temperature stability. Sophisticated future-looking algorithms make temperature ramping faster and smoother. These high-end features are unique to ESPEC. Additional improvements in refrigeration and heater operation will make the next generation of ESPEC chambers the most energy efficient ever.

Additional capabilities

  • Store up to forty programs, as well as three different constant-mode set-ups.
