It is applicable to such test as drying,cure melt,sterilize in industrial and mining enterprises as well as in laboratory and scientific research institute. 
II.Features: 
1 , The working chamber is made of high quality sheet steel or corrosion-restistant stainless steel,safe and easy to use. 
2 , Intelligent temperature controller is based microprocessor with PID parameters controlling function.Digital display of set and actual temperatures. High temperature controlling accuracy and reliability. 
3 , Hot air circulation system is consist of low-noisy fan and optimal air duct, reaching a uniform temperature inside the working chamber 

Notes:
1.DHG Series has timing function. And the range of timing is 0 to 9999 min. The temperature control precision is 0.1ºC and the temperature fluctuation is ±ºC,"RT" stands of room temperature.
2.Except main voltage of model 9623A, 9426A and 9626A are 380V, 50Hz, the others are 220V, 50Hz
3.(A) have "A" and not have "A". And "A" means stainless steel working chamber, has the window in the door. The not have "A" means zinc or ordinary steel working chamber, has not window.
