Features of hot air circulation oven

The outer shell is made of high-quality cold-rolled steel plate, and the surface adopts electrostatic spraying technology, which is novel in appearance, sturdy and durable. The studio is made of high-quality stainless steel plate or cold-rolled steel plate, which has the advantages of high temperature resistance, corrosion resistance, and no black smoke. The movable pull-out net frame increases the storage space for the materials in the box. There is a double-layer tempered glass observation window in the middle of the box door, which can observe the heated objects in the working room at any time.

Precautions for using hot air circulation oven

1. The hot air circulation oven must be placed in a dry and horizontal place indoors to prevent vibration and corrosion.

2. Pay attention to the safe use of electricity, and install a power switch with sufficient capacity according to the power consumption of the hot air circulation oven. Choose enough power wires and have a good grounding wire.

3. The mercury thermometer type thermostat with electric contact should connect the two wires of the electric contact thermometer to the two terminal posts on the top of the box respectively. Insert an ordinary mercury thermometer into the exhaust valve to open the exhaust valve hole. Adjust the electric contact mercury thermometer to the required temperature and tighten the screws on the steel cap to achieve the purpose of constant temperature. But be careful not to turn the indicator iron out of the scale when adjusting.

4. After all the preparations are ready, put the sample into the hot air circulation oven, then connect and turn on the power supply. The red indicator light is on to indicate that the oven is heated. When the temperature reaches the controlled temperature, the red light is off and the green light is on, and the constant temperature is started. In order to prevent the temperature control from failing, it must be looked after.
