GDH,GDHS High/Low Temperature Experimental Oven I.Applications: It is applicable to such test as experiment and detect for high/low temperature or damp heat environment in industrial and mining enterprises as well as in laboratory and scientific research institute. II.Feature: 1.The working chamber si made of stainless steel and has circle arc shape ,which is easy to clean 2.Whole close compressor is French ,which run sreadily and reliability. 3..Intelligent temperature controller is based microprocessor with PID parameters controlling function .Digital display of set and actual temperatures. High temperature controlling accuracy and reliability 4.Air circulation system is consisted of low-noisy fan and optimal air duct, reaching a uniform temperature inside the working chasmber. 5.There is a 30mm-diameter testing hole nearside the chest, which is applied by the testing power line and signal line. 6.The chamber also can use the printer.
