The graph on the picture seems to be up to 96 seconds, is it capable of showing data/readings for a longer period of time?

It goes to 24 hours but you can’t choose it does it automatically for you. I expected to be able to see the last 96 seconds on the graph but after 96 seconds it switches to 0-48 minutes and then larger intervals but the bar on the graph averages in more time to represent one bar as time goes on. It is not all that useful because once it gets past 96 seconds small changes in air quality sort of get lost to being averaged out with the other chunk of data for each bar on the graph. If you leave it on for hours at a time the graph is all pretty much just equal bars bc changes get averaged out too much.

can this device store monitored data and can I transfer monitored data to computer?can I use it for outdoors?

Store: No, Transfer: No, Outdoors: Yes, but don't get wet and do not use if it maxes out the particle count as it can damage it. But if you're maxing it out, you should probably not be outdoors at that location :)

how long does each sensor last? Several sensors from M10, M1000's only last for 3 years, do that apply to this one too?

The sensor life is 3 years for particle sensor

How do you perform initial calibration? The manual says leave it outside for 6 hrs but doesn't say if it should be on or in a specific mode.

Please keep it powered off in a ventilated place for 6hrs for calibration.
