An oven is a device that uses a heating wire to heat and dry objects. It is suitable for baking, drying, heat treatment, etc. in the range of 5~300°C (some 200°C higher) than room temperature. The sensitivity is usually ±1°C. It has many models, but its basic structure is similar. It is generally composed of three parts: the cabinet, the electric heating system and the automatic temperature control system. Its use and precautions are summarized as follows: 1. The oven should be placed indoors in a dry and level place to prevent vibration and corrosion. 2. Pay attention to the safe use of electricity and install a power supply knife with sufficient capacity according to the power consumption of the oven. Use enough power leads and have a good ground wire. 3. The oven with the electrical contact mercury thermometer thermostat shall connect the two wires of the electrical contact thermometer to the two terminals on the top of the box. Another common mercury thermometer is inserted into the exhaust valve. (The thermometer in the exhaust valve is used to calibrate the mercury thermometer for electrical contact and to observe the actual temperature inside the box.) Open the vent hole. Adjust the electrical contact mercury thermometer to the required temperature and fasten the screw on the steel cap to achieve the purpose of constant temperature. However, care must be taken not to turn the indicator iron out of the scale when adjusting. 4. When everything is ready for work, put the sample into the oven, and then connect and turn on the power. The red indicator light indicates that the inside of the box is heated. When the temperature reaches the controlled temperature, the red light goes out and the green light comes on, and the constant temperature starts. In order to prevent the temperature control from failing, you must also look after it. 5. When placing the sample, attention should be paid to the arrangement not too dense. There should be no test specimen on the heat sink so as not to affect the upward flow of hot air. Do not bake flammable, explosive, volatile, and corrosive materials. 6. When it is necessary to observe the sample in the working chamber, open the outer door door and observe through the glass door. However, it is better to open the door as little as possible so as not to affect the constant temperature. Especially when working above 200°C, opening the door may cause the glass door to snap and burst. 7. In the oven with air blowing, the blower must be turned on during heating and constant temperature, otherwise it will affect the uniformity of the temperature in the working chamber and damage the heating element. 8. The power should be cut off in time after work to ensure safety. 9. Keep the inside and outside of the oven clean. 10. When using, do not exceed the maximum temperature of the oven. 11. In order to prevent burns, special tools are used to take samples. For detailed introduction to the oven please see: http://?id=213&page=2
