The ET2 temperature test chamber is similar to our ET1 model with an additional 3" of vertical workspace. Like the ET1 model, the chamber's controller is separate from the chamber chassis. A 6 ft. cable connects from the chamber to the controller. The ET2 chamber comes standard with a window hinged door, circular ports on both the top and bottom of the chamber and both a chamber and user probe. The chamber uses horizontal air flow with convection style heating, has a temperature range of -184°C to 315°C and incorporates a user adjustable bi-metal thermostat for upper temperature limit protection in addition to user adjustable software upper and lower temperature limits. The chamber uses the PC100-2 temperature controller - a dual sensor, single channel, 1/4 DIN controller with a user-friendly interface as well as an IEEE488 (GPIB), RS232/RS422/485 interface for remote control capability.
