This CO2 monitor is a desktop type unit designed for fast and accurate measurement of CO2 level, air temperature and humidity. The built-in Non-Dispersive InfraRed (NDIR) sensor provides long term stable monitoring. User can set 2 sound limits: upper & lower limit. It has an audible & visual sound to give warning when CO2 concentration exceeds the limit. Once CO2 level goes back to normal the sound will automatically stop, sound can be also be stop by pressing any key. Features: Long time drift compensation Manual CO2 calibration with calibration indicator With power adaptor output voltage indicator via LCD and LED light Factory pre-calibrated With CE Marking, passed the standards and had been approved by Europen Directives for health & safety Perfect to be used to monitor air quality in schools, office buildings, greenhouses, factories, hotels, hospitals and anywhere that high levels of carbon dioxide are generated Specifications: Response: >CO2:lt;2 mins (90% step change) Air Temp.: <2 mins (90% step change) .Air RH%: lt;10 mins (90% step change) Good: lt;700ppm (can be set by user) Normal: 700~1000ppm (can be set by user) greater -Poor: >"Normal" Max/Min function sound: >1000ppm (programmable by user) Operating Condition: -10~50C, 5~80%RH (Be sure to avoid condense) Storage Condition: -20~60C, 5~90%RH (Be sure to avoid condense) Power Supply: Power adaptor (5V/0.5A output) Set Includes: 1 x C02 Desktop Monitor 1 x Power adaptor 1 x English Operation Manual Standard White Packaging Box

No proper calibration
This would be a good and useful device, but the information about calibration and the manual calibration procedure do not make any sense. So, depending on how well the factory calibration was carried out and how long the device remains calibrated, it may show reasonable numbers, otherwise, it is not more than a toy.The instructions explain that there are two modes of calibration:1) automatic baseline calibration, which is always on by default: according to the instructions this "is to calibrate the meter at the minimum CO2 reading detected during 7.5 days continuous monitoring (power on). It is supposed that the ventilating area exists [sic!] fresh air with CO2 level around 400ppm during a period of time" Of course this is completely useless, since no-one can guarantee that there will be air with 400ppm but not less at least once a week.2) manual calibration: again this requires a reference CO2 concentration of 400ppm. They suggest to do this outdoors, but of course unless one has a nother meter, there is no guarantee that the concentration is 400ppm and not significantly more or less. Also, this device only works when connected to the mains adapter so it is hard to do the calibration outside. Also this kind of calibration needs about 30 minutes to be carried out.Also, they do not indicate how fast the device can be expected to drift away from being calibrated.

Has worked flawlessly for 2 years and counting
This product has worked flawlessly for me over the last 2 years (has been on and in active use every day for over 2 years) very pleased. Very sensitive; breathing near it starts to raise the level and using a soda stream near it sends the level very high and sounds the alarm.

Basic accurate CO2 monitor
CO2 monitor, works well, fast start up, doesn't have any additional functions seems to be pretty accurate.
