Does the fluke 985 detect humidity and report it as a particle count or does it have a humidity filter inside?
The Fluke 985 Particle Counter does not detect humidity, but if you plan to test for humidity you can look at the Fluke 971: Temperature Humidity Meter.

Is there a setting that will allow the 985 distinguish between which particles it is detecting? Possibly if it picks up CO2. I originally wanted a Fluke 975 but they are discontinued, so we bought this one. Thanks
The Fluke 985 Particle Counter does not define the size, or other parameters, of particles only count.

Can readings be streamed live over the USB/Ethernet connection? Or can data only be exported via USB/Ethernet after recording?
Data from the 985 cannot be streamed live via USB or ethernet, but you can view data trends live on the 985 display in the Trend Data mode. And once a recording or session is complete, you can then move the data to a PC either with the USB cable, USB flash drive or ethernet cable. With the latest firmware revision you can select the data to be exported as a xls or tsv format.
