Amprobe CO2-100 Handheld Carbon Dioxide Meter
Good features and seemingly durable
Product is relatively easy to setup and use. I have not tried to calibrate as I expect it's factory calibration is still solid after only using for a couple of days. Do wish it didn't take 30 seconds to be ready to use and I have yet to be able to get the unit to power off manually. However, its is great to have not only temp and humidity but Dew point and Wet bulb as well. That is handy. Being able to get an average of all those readings is a definite plus. Good Product all around so far.

Perfect amount of info...
I love this light weight CO2 meter. Has all the numbers displayed in large on a clear screen. Not too much info on the screen at once. Not many buttons on meter, but all the info necessary for monitoring the IAQ. I wish it had a stand on back of meter so that i can leave it standing in a room on a piece of furniture for 15 min., and not be worried someone in the office will brush the furniture and cause it to fall. I would surely urge anyone in IAQ field to buy this.

This product is easy to use and read
While just purchasing my first home with a gas furnace, we had problems with it not working when we moved in. The pilot light wasn't working properly. Knowing it was gas and worried about the odors being omitted we purchased this tool to keep an eye on it. The ease of using it and understanding what the readouts meant help us be sure that there wasn't too much bad carbon dioxide in the air.

the simple misprint in the manual is that you must press "^" and "cal" together, not the downward facing arrow for calibration, once you do that it works wonderfully

Wrong instruction for calibration
Meter is good, easy to use and reliable. Odd thing is that you can never calibrate the CO2 Sensor if you follow the instruction. Amprobe should check for the mistake and revise the manual.

Consistent calibration and fast updating
I use this tool to check environmental CO2 conditions in theaters and in the field. The range is good with humidity readings that went to 3% in Colorado sub-alpine desert and CO2 readings that topped the 9,999 ppm limit in productions.
The carrying case is a bit large but made to carry other accessories. I would have liked it to include the 110V transformer. Take the unit when you look for a transformer; it is a smaller DC plug than expected.
