Air quality monitoring |
|
We wanted to be able to measure a medium-sized room (40' x 40')
fairly quickly and accurately and inexpensively. |
We eventually determined that the part of the training area
nearest the kitchen needed a second monitor. For most |
houses a family could move one monitor around as needed. We
wanted to be able to measure continuously all day. |
The temperature would drive whether we heat or cool the training
area - our objective is to keep the temperature as |
constant as we can. Similarly, the humidity in the training area
changes over the duration of a class and would drive |
the use of the humidifier or the de-humidifier. The three PMs
(stands for Particulate Matter) usually measure the amount of |
smoke (quite the concern in these days and weeks of wildfires
here in California) and the numbers refer to the size |
particles being measured (10, 2.5 and 1 microns). We also
monitor formaldehyde and TVOC which is Total Volatile Organic |
Compounds - either or both probably being a sign that the air
filters need changing. This is model EGVOC - about $130 |
