Monitor Lacks Robust Design
I bought one of the Dylos monitors several months ago and I was initially quite impressed. I have the more advanced, 0.5 micron model, and it reported count readings that seemed to correlate with time of day (lower reading at night) and activity (e.g. higher reading when I am dusting) However, I was not as impressed after it started to report readings that were inexplicable. For example, after a while, the reading seem to rest on a plateau of about 2200 (which signified bad air quality), whereas before it should normally read 700. I taped a piece filter paper to cover the ingress and the reading will drop to 1700. So I called up Dylos customer and technical support, who were very friendly and helpful. However, the answers I got from them were not entirely encouraging. First, the monitor had no calibrating function. So, if you suspect the reading is too high (as in my case) or too low, you are just left wondering; and of course, once you think a test or measuring tool is...
It does everything I expected
I bought the .5 micron model. The reason I bought one of these is to test the exhaust from different HEPA vacuum sweepers I have. All I wanted to know is what works and what doesn't... meaning what vacuum sweepers put out readings of "0" particles down to 2.5 microns on that scale reading and "0" particles down to .5 microns on that scale reading in the vacuum's exhaust air. I simply put the Dylos near the exhaust port on the vac and waited for the results.
My lead and asbestos safe vacuums are easily confirmed to the "0" readings as they should be, where other HEPA vacs I own were confirmed to blow all kinds of potentially toxic dust out their exhaust ports even though they were "HEPA" vacs. And yes, we have since trashed every HEPA vac that did not blow clean air. Some of the "hepa" vacs were blowing out as much as a staggering 670,000 particles per hepa-filtered cubic foot of air... it was really eye-opening.
The Dylos told us everything we needed at a very...
great
I have owned this product for 3 years and for most of that time it has been on. it works great and I am able to check my IQAIR to make sure it puts out 0/0 and if it does not i know the hepa filter needs changed.
i only rate it 4 stars because I got the PC version but it does not seem to work with any USB>serial converter so i cant use the function
I would pay more for a blue tooth or USB version, the USB i could put a blue tooth in and log the data 24x7 on my server.
its a great product and has proven reliable, with a tweak to the interface would be nice. no PCs(laptops and newer mother boards) come with serial anymore.
