The ET1 temperature test chamber is our smallest chamber based on overall exterior dimensions. To accomplish this, the chamber's controller is separate from the chamber chassis. A 6 ft. cable connects from the chamber to the controller. The ET1 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. Sun also offers the ET2 model temperature chamber, which is similar to the ET1 with an additional 3" of vertical work space.
