J R5.0 out of 5 starsEXCELLENT!Reviewed in the United States on October 22, 2012Verified PurchaseExpensive but accurate! Reads correct temp within a degree. % humidity also seems accurate. GRATE to know (+ or - 75) CO2 reading is accurate. I recommend this to anyone that wants to know CO2 of indoor environment! Buy this NOT Acu Rite.
STA4.0 out of 5 starsAccurate, wish backlight would stay onReviewed in the United States on February 16, 2023Verified PurchaseI have access to an industrial quality ambient CO2 meter and checked the CO100 against it, difference of 10ppm at 660ppm levels. I give this 4 stars because the backlight helps keep the rather dark LCD visible, and this is plug-in only. Why not have it possible to stay on?
As well, unplugging it momentarily wipes the time and date setting, less of an issue but also not as satisfying
Matt5.0 out of 5 starsFive StarsReviewed in the United States on March 31, 2018Verified PurchaseWorks really well. Immediately reacts to increased CO2 levels.

jrp5.0 out of 5 starsWorks well and quick to react - provides a lot of reassuranceReviewed in the United Kingdom on February 18, 2017Verified PurchaseWorks well, gives us a lot of reassurance as our baby is in a small nursery, this lets us know that the ventilation is working well and the humidity levels aren't getting too high / low for her. Would recommend.LD4.0 out of 5 starsWorks well but design could be better at the price!Reviewed in the United Kingdom on November 15, 2015Verified PurchaseThis CO2 meter works well but the design could be a little better. It is also pricey, hence the 4 star rating. We use it all the time now to ensure the rooms we spend a lot of time in are well ventilated. Everyone is so keen to hermetically seal their house to prevent heat loss, but forgets that ventilation is essential to move the CO2 out, or levels will rise and end up making you feel groggy in the morning and headachy. This unit would benefit from having a back light function and a back up battery as it has to be permanently plugged in to mains and the cord is not very long.
