Note:

- This instrument is not for constant safety monitoring. For your personal safety, do not use it as a monitoring device.

- Carbon monoxide is a highly toxic gas. Before using this instrument for detection, ensure personal safety protection.

- Do not use the instrument in environments with relative humidity exceeding 80% (condensation).

- Avoid using the instrument in enclosed spaces, as gases there may have gathered into explosive or toxic mixtures.

- Ensure that the gas concentration does not exceed 20% LEL (Lower Explosive Limit).

- Due to manual measurement, please allow a difference of 1-3mm.
