Oven is a device that uses steam, electricity, far infrared and electric steam to dry objects. It is suitable for baking, drying, heat treatment, etc. which is 5~300℃ higher than room temperature (some are 200℃ higher), and the sensitivity is usually 2℃. It has many models, but the basic structure is similar, and generally consists of three parts: box, electric heating system and automatic temperature control system. Its use of ovens, matters needing attention in ovens and safety specifications for use.

1, put the oven, oven, and do not put inflammable and explosive articles around the equipment.

2. Pay attention to the safe use of electricity. The oven should be placed indoors in a dry and dry place to prevent vibration and corrosion. Choose enough power conductors and have good grounding wires.

3. For an oven with an electric contact metal mercury thermometer, the two wires of the electric contact thermometer should be separately connected to the two terminals on the top of the box, and an ordinary metal mercury thermometer should be inserted into the exhaust valve (the thermometer in the exhaust valve is used to calibrate the electric contact metal mercury thermometer and observe the actual temperature in the box). After opening the hole of the exhaust valve to adjust the electric contact metal mercury thermometer to the required temperature, tighten the screws on the steel cap to achieve the purpose of constant temperature, but it is necessary to pay attention to not turning the indicating iron out of the scale when adjusting.

4. When everything is ready, put the sample into the oven, and then turn on the power supply. The red indicator light indicates that the box has been heated. When the temperature reaches the controlled temperature, the red light turns off and the green light turns on. In order to prevent the temperature control from failing, it is necessary to take care of it.

5. When placing the sample, it should be noted that the column should not be too dense. The sample should not be placed on the radiator plate, so as to avoid affecting the upward flow of hot air. It is forbidden to bake flammable, explosive, volatile and corrosive items.

6. When it is necessary to observe the samples in the office, you can open the external door and observe through the glass door. However, it is advisable to open the door only a little to avoid affecting the constant temperature, especially when working above 200℃. Opening the door may cause the glass door to burst due to sudden cooling.

7. In the oven with blower, the blower must be turned on during the process of heating to a constant temperature, otherwise the uniformity of office temperature will be affected and the heating elements will be damaged.

8. Turn off the power supply in real time after work to ensure safety.

9, inside and outside the oven to link clean.

10, when using, the temperature should not exceed the highest temperature of the oven.
