Precautions for sulfur dioxide test chamber
1. The sulfur dioxide test chamber should be installed in a room with clean air, no direct sunlight, no strong electromagnetic field and radiant energy, and small changes in ambient temperature.
In order to ensure the temperature control accuracy of the carbon dioxide incubator, it is recommended to use it in the environment of 15 °C - 25 °C.
2. When the cylinder pressure is less than 1Mpa, it should be replaced in time. When replacing the cylinder, the cylinder switch should be closed first, the pressure reducing valve screw shaft should be loosened, and the pressure reducing valve should be removed and reinstalled on the new cylinder.
3. When the difference between the ambient temperature and the set temperature is less than (RT 5 °C), the air conditioner is used to reduce the ambient temperature.
4. During the whole process of the culture, there should be no obvious change in the ambient temperature, otherwise the carbon dioxide will be caused by the change of the ambient temperature. The temperature control in the incubator is not allowed.
5. Read the instruction manual before starting the machine, master the correct use method, pay special attention to the cylinder before opening, be sure to loosen the pressure reducing valve to prevent the gas hose from blasting.
6. When using the machine for the first time or after reusing the machine for a long time, it should be operated according to the requirements of Articles 1 to 3 of the method of use, especially when it is officially cultivated.
7. When opening the inner door of the box, first turn off the carbon dioxide control switch. After closing the door, when the CO2 concentration display shows “0.0”, turn on the CO2 control switch.
