Temperature Test Chamber - Model EC02The EC02 temperature testing chamber was expressly designed to work with computer controlled test setups without the need for the addition of "outside boxes" and attending wiring/cabling to configure a computer-controllable environmental system. In addition, the EC02 can be used as a complete stand-alone environmental system that does not require a host computer. The temperature controller used in the EC02 supports a manual mode of operation wherein the user can program the execution of up to 10 time/temperature segments via the 16 key keyboard. Automatic cycling and audio-visual indicators complete the package so that a separate computer or "programmer" is not required for automatic scanning operation. The remote mode offers unlimited time and temperature combinations via the IEEE-488 bus and RS232 port in addition to the 10 time/temperature scan mode. The chamber may also be controlled through a PC via the RS232 port and the IEEE-488 interface. The EC02 command structure fully supports control of timing, temperature, safety limits, heat/cool enable, auxiliary outputs(2), and auxiliary input. A special command set is supported allowing bidirectional RS232 to IEEE-488 transparent communication, often used for special test fixture communication requirements. Additionally, the PID coefficients used in the EC02 temperature control algorithm are user adjustable via RS232 or IEEE-488. Safety features of the EC02 chamber include a hardware watch-dog timer to protect against microprocessor malfunction and other forms of loss-of-program control, short/open probe detection, IEEE-488 bus time-out, settable user software Upper Temperature Limit and a user-adjustable, bi-metal mechanical or electronic failsafe mechanism.

EC0X Models

The chamber has a temperature range from -184°C to 314°C (using LN2) or -73°C to 314°C (using LCO2) and may be equipped with options such as 1" to 4" circular ports, shelves, electronic failsafe, hinged and window doors.

The model EC02 benchtop temperature cycling chamber is designed to be adaptable to your system application. If you would like a quote or have special requirements, please call Sun Electronic Systems for solutions.


EC0X Programming Examples
Single Set point example

soak at 85C for 30 min:

85 TEMP (enter 85C set point)
30 TIME (soak at 85C for 30 min.)

Multiple Set point example

Execute 10 cycles from -50C to 85C and
soak for 30 min. at each temperature:

-50 SCAN TEMP 0 (-50C set point)
85 SCAN TEMP 1 (85C set point)
30 SCAN TIME 0 (soak at -50C for 30 min.)
30 SCAN TIME 1 (soak at 85C for 30 min.)
10 SCAN TIME - (execute 10 cycles)
SCAN TEMP SCAN TIME (start program)
