Faculty of Engineering, University of answering all questions about buying "microwave" in the subject that can be understood easily. And you know the market and the question of whether a vendor such as digital and conventional form is better.

The radiation that is plastic with a durable and better kind of paper?

          Waves in the microwave electric field with high frequency waves. To the mass of water inside the food warm. Thus the radiation. The plate electrodes, which must be metal. The sheet of paper or plastic sheet that is it. Only acting as insulation plate. As for durability and cleaning inside the microwave oven. Plastic have several advantages over paper.

There is no button lock with key lock. Which is better?

          The second key difference is not in use. The button with the lock will have advantages over the traditional setting that is not locked. It has the power of the microwave oven in a fixed time has been set.

 Devices that have ventilation holes on the top and side lot. With no ventilation holes. Or less. Which is better?

          First, to understand it. Need to understand the nature of the air. The hot air will always rise above, so that the device has ventilation holes on top. Would result in a better cooling of the machine. The temperature of the hot work is not the same machine with no ventilation holes in the sides for ventilation. Intended to replace the cold air from flowing into the hot air to float to the top.

 Mesh panels on the doors shut. What's up?

          Mesh panels on the doors shut to prevent high-frequency electric field within On the outside than the standard set. This is the energy security of the human electromagnetic field. With access to all sides. (Excluding doors) made of glass or plastic. The need to mesh panels that are electrically conductive. To prevent such an electric field.

 Plastic with a glass door. Which is safer?

          When plastics are damaged or broken. It is less dangerous than glass. If you consider cleaning it. Glass has several advantages over plastic.

 To tell you the power to solve real-watt power. To have a High / Low Which is better?

          Sheer numbers would be better than the 'high or low' because the user will know the power and heat than And more convenient to get cooking.

 Why some microwave. The hot dishes. While some are not hot?

          This includes many factors such as temperature of the food. Period of heat. The material of the container. Because the microwave. (Without the grill and heat sources on top) will work on the basis of the polarized electric field. The mass of water inside a hot meal, so if you use a container made of metal. Electric field will not be able to penetrate into the container.

 If you stare long microwave. It is dangerous?

          May be dangerous. Depending on the individual. If you do not have a mesh door to prevent

 Microwave lifetime or not?

          All kinds of electrical equipment for use. The long or short. Depends on the use and maintenance.

 Digital microwave. Better is that true?

          The digital system has both advantages and bad. And related to the price of the machine with a digital clock may not be necessary. Also power consumption when not in use as well. It has the advantages that can be set up by the addition of digital microwave may be easier than normal as well.

 Microwave with glass. Necessary or not?

          However, it must be like glass or plastic door of the microwave oven is no different. And does not require glass. Except that the user may be clumsy, and the microwave door.

          The microwave door is better or not. Not associated with a glass or plastic. However, depending on the mesh is attached to the door.

 The staff recommended to buy a microwave. I enjoy the heat longer than other brands I should consider or not consider the last 3 years?

          Do not have a microwave to heat it. (Except for the grill, microwave) and a metal plate that serves as the polarity of the electric field. They last for more than a bad one, so this issue is not an issue to be considered a warranty in any way.
