3. Check the function of the toxic gas detector. Whether the instrument is in good condition mainly depends on whether it has multiple functions, such as data transmission, fall alarm, expiration of service reminder, etc.

4. Check if the response speed of the instrument is fast. When detecting data, once the value exceeds the standard, there will be a critical moment where every second counts. Sometimes it only takes one second to avoid potential safety accidents. Therefore, the response speed of toxic and harmful gas detection equipment is very important.
