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 a small change in the surrounding temperature difference. In order to ensure the temperature control accuracy of the carbon dioxide incubator, it is recommended to use it in an environment of 15 ℃ -25 ℃. 2. When the cylinder pressure is less than 1Mpa, it should be replaced in time. When replacing the cylinder, the cylinder switch should be turned off, the screw shaft of the pressure relief valve should be loosened, and then the pressure relief 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 ℃), apply air conditioning to reduce the ambient temperature. During the whole cultivation process, the ambient temperature should be kept unchanged, otherwise the carbon dioxide will be caused by the change The temperature control in the incubator is not accurate. 4. Read the instruction manual carefully before starting up, and master the correct method of use. Pay special attention to loosen the pressure relief valve before opening the cylinder to prevent the gas hose from bursting. 5. During use, the output pressure of the pressure-reducing valve and the flow rate of the two flowmeters should be constantly monitored, and the various valves in the control box must not be twisted at will. If there is a deviation in the concentration in the carbon dioxide incubator, the reasons for the inaccuracy of the relevant values ​​should be found before adjustment. 6. When using this machine for the first time or reusing it for a long time, it should be operated in accordance with the requirements of Articles 1 to 3 of the method of use, especially for pollution inspection during formal cultivation. 7. When opening the door inside the box, the carbon dioxide control switch should be turned off first. After the door is closed, the CO2 control switch should be turned on when the CO2 concentration display shows "0.0". 8. When opening the glass door, the operation method 3 should be used to prevent "overshoot" due to accumulation when the temperature and CO2 concentration in the box recover. 9. The sulfur dioxide test chamber should have a good grounding device to ensure safety.
