Extech EA80 EasyView Indoor Air Quality Meter and Datalogger - CO2, Temperature, Humidity, Dew Point, Wet Bulb, NDIR Sensor, 20,000 Data Set Logging, Backlit LCD

Poor quality. Eats the batteries like nobody business. Wand cord is way to thin and fragile.

I imagined this would be a similar size to the TSI IAQ meters and Graywolf sensing meters that I used to rent for IAQ surveys, but it is not. It's smaller (think hand-held) and the wand is also tiny (a little bit bigger than a standard highlighter). It has a built-in stand so that you can lean it on a surface while collecting measurements. The meter itself is green but has a bright orange case for if you accidentally drop it. Takes 6AAA batteries (comes with) and software for graphing data points for use in reports. Comes in a fairly large black plastic case - I use it to hold the IAQ meter and a moisture meter. Haven't used it in the field yet, but messing around with it in my house and outside, it looks like it will fit my needs for limited IAQ surveys.
