1. Scope of application
This new product is widely used in the drying, heat treatment and heating of test samples in laboratories of industrial and agricultural production, scientific research, medical and health units, etc., but it is not suitable for volatile, flammable and explosive items, so as not to cause explosions.
2. Product structure and characteristics
The lower part of the working room of this product is equipped with a heating wire, and the left side is equipped with a blowing device. The thermometer controls the constant temperature and height. When working, the air flows in from the air inlet at the bottom of the box, is heated by the heating wire, and then flows into the working room through the blowing device. Then it is discharged from the vent hole on the top of the box. There is glass fiber as insulation material between the studio and the shell, the shell is made of steel plate, the surface of the box is treated with oil spraying, the studio is mainly made of galvanized sheet and stainless steel plate, and there is an observation window made of tempered glass in the middle of the box door .

4. How to use
(1) Instructions for use
1. Before turning on the power, please make sure that the switch is set to the "off" position, and check whether there is an open circuit or leakage.
2. Because there will be a slight smoking process when heating for the first time, it is recommended not to put the sample before the official use, close the door, unscrew the exhaust cover on the top of the box, turn on the electric heating switch, the blower switch, the indicator light is on, Put the heating switch on the "slow" gear, set the temperature controller at 100°C, and the temperature inside the box will start to rise. When the temperature rises to 100°C, the temperature controller will automatically maintain the temperature, and then you can cut off the power supply, open the door to dissipate heat and loose smoke.
3. When in official use, first put the sample on the shelf, close the door, unscrew the exhaust cover on the top of the box, and after connecting the power supply, turn on the electric heating switch and the blowing switch. You can choose to heat up quickly or slowly when using. Then set the temperature controller to the required temperature, and then the temperature inside the box starts to rise. When the temperature is constant, the heating gear should be set to the "slow" gear, so as to ensure the fluctuation of the constant temperature and the uniform temperature in the box.
4. The sample should not be placed too crowded during use, so as not to affect the convection in the box. When placing the box, please ground the box effectively according to the regulations to ensure safe use. Do not touch the electrical circuit on the left side of the box with your hands or wet cloth when the power is on.
5. When the temperature rises, please do not splash water on the observation window of the box door to prevent the glass from bursting due to cold.
6. This series of Drying Ovens are non-explosion-proof products.
7. Please do not put volatile, flammable and explosive items into the box for heating to prevent explosion.
(two), maintenance and repair:
Daily maintenance of equipment:
1. The drying box should always be kept clean. The door glass should be wiped with a soft cotton cloth. Do not wipe with corrosive chemical solutions to avoid chemical reactions and scratches on the glass.
2. If the drying box is not used for a long time, it should be coated with neutral grease or vaseline on the electroplated parts to prevent corrosion, and put a plastic film dust cover on it, and put it in a dry room to prevent the electrical appliances from being affected by moisture.
