Dylos Laser Particle Counters | Sylvane

i see the dylos in the vdo come with power converter but i checked in amazon the product compatible only with electricity 110v or 120v, my country uses 220v is that mean i can not use it at home? or where can i find the product designed for oversea uses ?

how i calculate pm2.5

[@rickrude6301]

I have the Dylos DC1700 0.5 / 2.5 micron model that is battery operated (and or) ac powered. It is sure worth it to get the battery operated unit. If you want to convert your non battery operated DC1100 to battery operated get an 8 AA cell battery holder from ebay ($5) or RadioShack. Many thrift stores have ac adaptors for a few bucks. Find one that fits the jack on you DC-1100. Cut off the wall ac adaptor, we just want the wire and dc connector. Strip the 2 wires at the ends and twist them together to join the red and black wires of the battery holder and use some tape around the connection. The tip of the connector is positive. A multi meter comes in handy here. The 8 AA battery holder will provide 12 volts if used with 1.5 v alkaline batteries, the Dylos only takes 9 volts dc, so only use 7 1.2v rechargeable AA batteries instead of 8. Make a dummy battery from a steel bolt or a paperclip. Now you can use your DC1100 as a portable battery operated unit! I have been taking mine everywhere to check air quality.

very interesting, so I could use a 7.2v Lipo......but which Ampers do the Dylos need? thanks!

Why not use a 9v battery?

[@rickrude6301]

Joe Shmoe You could with 9 v snap leads wired to a 5.5 mm jack. The 9v battery would not hold as much power as the AA cell holder will. An interesting note is that the Dylos will draw power from the external battery even when it is turned off, so always unplug your battery when not using the Dylos.

It only measures particle size, not what kind of particle. So it could as well be moisture it measures, from cooking or an air moisturiser, which is harmless. So it is Not an air quality monitor, only a pariticle quantity and size monitor. Because you don't know what it measures, its use is limited.

Well yes and no. The only way to find out what is truly in the air would be to use a spore trap like they do when testing for mold and send it in to a lab and someone could get under a microscope and identify. This is costly and impractical on a regular basis. Particle counters could be considered a “surrogate” testing method. If we have high particle of PM2.5 we can assume some of the particles are hazardous. In fact, it does not matter what the particle is. PM2.5 particles can bypass lungs natural defenses and enter directly into the blood stream circulating to the brain and other organs. Regardless of what the particle is it should not be in your blood stream. By placing an air purify with HEPA filtration and dropping the particle number, you can reasonably say the air quality is improving. With this thinking I would say yes, particle counters can be used for an air quality monitor.

You pointed to the wrong size in the very beginning.

If u want to share the knowledge... How about a heads up inside the unit. Like can I get the cheaper one and dig to find unpopulated rs232 headers on its board? 😂
