The experimental oven is mainly suitable for drying, heating and heat treatment of product test articles in industrial and agricultural production, scientific research, medical and health, laboratory and other units. The temperature of the drying oven can be adjusted from 10 °C to 300 °C. Temperature and automatic constant temperature by means of the temperature control system inside the box. The digital display temperature controller is sensitive, reliable, easy to operate, and the digital display is more intuitive and clear. It is used in laboratories of universities, medical and health, environmental protection and other scientific research departments, as well as for labor, mining, agriculture, testing or production lines. The machine is equipped with a blast device, and the wind enters the working chamber from the air duct, which promotes the convection of the hot air in the working chamber, thereby having better temperature uniformity.
Experimental oven technical parameters:
Voltage: 220V
Total heater power: 2.4kw
Temperature range: 10-300° at room temperature
Temperature sensitivity: ±1
Studio size: 350 × 450 × 450mm
Dimensions: 500 × 810 × 780mm
Weight: 80kg
Experimental oven structure :
1. The cabinet is made of thin steel plate and steel. The glass fiber is used as insulation material between the outer casing and the working chamber. The glass door in the outer door can be used to check the working room.
2. All electrical circuits are installed in the control room on the right side of the cabinet. The temperature controller and the operation parts of each switch are outside the control room. The side door of the control room can be removed for easy maintenance.
Use and attention :
1. This type of drying oven should be placed at a dry indoor level, and the enclosure must be effectively grounded.
2. In the power supply line, the user should install an on/off switch corresponding to the dry box current for this box.
3. Each air-drying shelf in the working chamber of the drying box is provided for placing the test object, and the spacing of the whole shelf of the sample size adjuster can be placed. The test object should not be too dense to facilitate hot air circulation. Do not place the test object on the bottom plate to avoid burning the test object due to overheating.
4. This machine is a digital display temperature controller. When you choose to set the temperature for the day, press the temperature test setting number on the instrument panel to meet the required temperature number to start working.
5 The indicator of the temperature controller: The green light is the electric heater at work, the red light is the heating stop. When the temperature reaches the set temperature, the green light turns to the red light. After that, the temperature controller constantly flips the action, and the traffic lights alternately turn off. That is, the temperature is constant, but since the temperature inside the working chamber is not uniform even when the temperature is constant, even if the set temperature is reached, the temperature inside the box is at a constant temperature, and the residual heat may continue to heat up. This phenomenon gradually disappears after half an hour. stable.
6. When starting up, in order to obtain the accelerated heating time, the heating switch is driven to high temperature, and the two sets of heaters are heated at the same time. After reaching the constant temperature state, the heating switch can be driven to a low temperature, and only one set of heaters is saved to save power consumption.
7. When handling the sample, do not hit the sensor that protrudes into the working chamber to prevent damage and the sensor's temperature measurement head from causing control failure.
8. Before starting the machine, unscrew the top exhaust valve of the box about 10mm to facilitate the convection of the air inside the box and discharge the moisture and exhaust gas.
9. If you want to observe the sample in the working room, you can open the outer door or peep in from the glass door, but the outer door is not always open to avoid heat leakage, and when the temperature rises to about 300 degrees, open the door. It may cause the glass to cool and rupture.
10. This series of drying ovens are non-explosion-proof products. Do not bake flammable, explosive and volatile items to prevent explosion.
11. After use, the power must be cut off.
12. Once a fault occurs, it needs to be repaired before it can be used.
13. Please refer to the manual of the temperature controller.
