With more indoor air quality monitors becoming available every day, it’s becoming more and more difficult for monitors to differentiate themselves from one another and offer competitive advantages. In fact, while I’m happy to see so many choices now on the market, I often feel like there isn’t that much of a choice at all. This is down to the fact that most indoor air quality monitors offer a similar set of features and have few differentiating factors. This issue is only compounded by the fact that nearly all monitors on the market use sensors from the same companies, making…

Of course, getting a particulate matter reference sensor costs tens of thousands of dollars and is out of the question. However, without breaking the bank, I’ve been looking for something I can use for temperature and RH comparisons. After some looking, I settled on the Traceable 4040, an inexpensive (although still around $200 where I live) hygrometer that provides relatively accurate temp…
