Voltcraft CO-110 CO 2 meter
I brought this to check on the CO2 quality of the bed room whilst I sleep at night - and for that I chose this model as this one was the only one with an LCD screen. The rest on Digitec were all back lit. What you don't see in the display image is that on the left are bright Green, Orange or Red light (plus beeping) for the level of CO2. This means that it is not usable in a bedroom as the lights are so bright it will keep you awake. The other downside is that the system requires an external power supply you know the one's they used to give you when you bought a phone (iPhone charger anyone?). I solved this by using one of those battery power banks so a battery that cost more than the device just to power the CO2 meter :-(. Or you need to buy a separate phone charger - don't use a tablet charger you will blow this device
