Tips:  How to Maintain Carbon Dioxide (CO2) Sensor?

1. The instrument should be regularly maintained, do not drop it, and do not let the instrument inhale dust.
2. When the carbon dioxide analyzer is not in use for a long time, the power supply of the instrument should be turned off, and it should be stored carefully and protected from moisture and dust.
3. The model, specifications and parameters of the components in the original circuit shall not be changed during maintenance, and the original package shall not be changed. All repairs must be carried out on the well by professionals.
