一． Purpose 用 途
The electrothermal constant temperature air circulation drying oven is for the laboratories of the units such as scientific research, specialty universities and colleges, industrial and mining enterprises etc to test or produce, including the application of drying, solidifying, baking, wax melting and sterilizing etc.
电热恒温鼓风干燥箱供科研单位、专业院校、工矿企业等单位的实验室、化验室作各种试验、以及生产现场：如干燥、固化、烘烤、熔蜡、及消毒等应用。
二．Structure 结 构
The body of the oven is made of high quality cold-rolled steel plate, finished with electrostatic powder spraying; the coat is hard and firm, with strong rust resistance.
The working chamber is made of high quality stainless steel sheet, with round corner modeling which is smooth, fluent, and easy to clean.
Superfine glass wool thermal insulation material is filled between the body of oven and the working chamber, which is with nice heat preservation. It can ensure effectively the stability, accuracy of the temperature in the oven as well as the impact on environment.
The observation window on the door is made of double-layer tempered glass, the material heated in the oven can be observed clearly, meanwhile, the thermal insulation is well.
Reasonable hot air circulation channel is designed in the oven, so that the temperature distribution in the oven is more even, and the temperature rises faster; it is also equipped with adjustable air outlet, for adjusting the inlet and outlet air volume of the oven. If the gas ejected from the oven is with odor or poison, other pipe(s) can be easily connected to the air outlet for ejecting such gas to the designated place.
The temperature control is fabricated by microcomputer intelligent digital technology, which is with the functions of industrial PID self-adjustment and four-digit double LED windows indication, the temperature control is accurate with strong anti-jamming ability, and the operation is also convenient (please see the Operation manual of temperature controller for details).
箱体采用优质冷轧钢板，表面静电粉末喷涂，涂层坚硬牢固，具有极强的防锈能力。
工作室为优质不锈钢板，圆角造型、光滑、流畅、极易清洁。
箱体与工作室之间，充填超细玻璃棉隔热材料，具有良好的保温功能，有效保证箱内温度的稳定准确和对使用环境的影响。
箱门观察窗为双层钢化玻璃结构，能清晰观察箱内加熱的物品，又有良好的隔热效果。
箱内设计有合理的热风循环通道，使箱内温度分布更加均匀、温度上升更快；并装有可调节的出风管，用以调节箱内进出空气量。如箱内排出的气体有异味或有毒，出风管能方便的另接管道将气体排至指定地点。
温度控制采用微电脑智能数字技术制造，具有工业PID自整定和四位双LED窗指示功能，控温精度高、抗干扰能力极强，并且操作也非常方便（详情见温控仪操作手册）。

5. When this instrument works normally, the placement of the material in the oven shall not influence the air circulation, for the evenness of temperature in the oven.
6. The power supply is AC 220V 50HZ, 3-pole socket which is 16A or above must be applied, and with reliable grounding, no 2-pole socket can be used without authority.
7. The power line shall not be close to the back, do not put the instrument or other materials on the power line, for avoiding damage on the power line.
1、运输中注意不要在玻璃上用力，也不要碰撞箱体。
2、本设备落地后，应放置平稳如地面不平应予以修正。
3、请不要在阳光直射或高温潮湿的地方使用仪器。
4、本设备应远离电磁干扰源，并应将设备的接地线有效接地。
5、本设备在正常运行时，箱内载物摆放应不影响空气流通以保证箱内温度均匀。
6、电源为AC 220V 50HZ，必须使用16A以上三芯插座，并有可靠接地线，不得擅自使用二芯插座。
7、电源线不要紧靠后面，也不要让仪器或其他物品压在电源线上，以免损伤电源线。
五、Operation instructions to the product 产品使用说明
