In the current cabinet to test it has been vastly improved in order to develop the highest possible performance. But there are no companies or third can control the temperature, both hot and cold in the same. We invented a method to develop a test oven, hot and cold, controlled by a template, peltier. (Heating and cooling plates in a single plate) is a heating and cooling controls exposed with ventilation fan to increase performance. In terms of hardware, we have developed the new structure. Heat-resistant fiber reinforced into friends, reduce the rate of heat loss, and foam for cold store, and install the fan heat and cold. And installing an exhaust fan to blow the heat into the workpiece. The oven test specimens are also being developed to be available 24 hours for the plant industry.
