Hot Air Oven

  • Determination of various physical characteristics of different materials and products at elevated temperatures may be carried out by heating the test specimens to the appropriate temperature inside a constant temperature air oven and determining the required characteristics with the specimens kept under the same temperature. For this purpose the equipment needed for conducting the determination can either be kept inside the oven along with the test specimens, or, if this is not feasible because of certain constrains, by taking the heated specimens out from the oven and conducting the test in still air within the shortest possible span of time.



Hot Air Oven

  • The PSI Hot Air Oven (Universal Memmert type) with digital temperature controller has a test chamber of double walled construction. The inner walls are made of aluminum sheet (or stainless Steel) and outer walls of CRCA sheet. The space between the two walls is filled with mineral wool for insulation. The chamber is fitted with three adjustable perforated shelves for keeping the test specimen or the test equipment on.

  • The oven is heated electrically with the help of heaters placed in ribs on the bottom and sides of the chamber. An air-circulating fan is provided on the back of the chamber for even temperature distribution. The temperature inside the test chamber is indicated and controlled with the help of a digital temperature indicator cum controller.

  • The chamber is provided with two ports with adjustable openings for enabling natural change of air inside it by convection. These ports can also be used for providing electrical access to the test specimens kept inside the oven, if so desired.
