Guest guest Posted February 21, 2008 Report Share Posted February 21, 2008 Ian, An interesting low cost device. However, I find the need to measure 0.3 microns really important. Also, I like to look at the log normal distribution of the 5 sizes up to 5 microns. If one size it out of line, it indicates a potential problem. Lastly, looking at the counts on their data sheet, I would say that they either were testing in a really clean room, or their monitor is not very accurate. It would be fun to try it against a light house or an Arti. Might consider this later this year. Just to busy building an electric car right now.

Guest guest Posted February 21, 2008 Report Share Posted February 21, 2008 Ian,Air Test Technologies is managed in the US by Mike Schell, a very fine guy. He works out of Santa Barbara, and over a long career has worked for TelAire, Semco and Honeywell.I have not used this device myself, and am no sort of expert in assessing particle counters. But I would certainly rely on Mike for solid products.I saw the unit (briefly) at the ARI show in New York. It looked to me like a good candidate for preliminary screening at a very reasonable price. Probably the sort of thing a building owner or property manager might want to have, or maybe an annoyed building occupant or tenant.Lew--------------------------------------------Lew HarrimanMason-Grant ConsultingP.O.

Guest guest Posted February 21, 2008 Report Share Posted February 21, 2008 Lew, It sounds similar (in concept and price) to the particle counter used in AirAdvice.

Guest guest Posted February 22, 2008 Report Share Posted February 22, 2008 Bob, I think the display is in 100's of particles so you would tack on two extra zeros. It obviously lacks the features of a high end device, but I was thinking of a few good applications, such as those that Lew pointed out. By lacking the 0.3 micron size cut, it couldn't accurately field test a HEPA filtration device for example. I'd be curious to see how they perform side by side with a high end particle counters. Unfortunately it doesn't transfer data to a computer so it wouldn't be easy to graph it side by side. If anyone buys one, please give us all some feedback.
