      Why do you force me to buy a charger when you could have included it?

      Why does it not come with an $8 charger? I can't use the thing because I can't find a charger locally. At this point it is useless............

      Gerald, Thank you for sharing your feedback about the CM-501. We’ve shared your notes with our engineering and management teams for consideration. When we sent samples out for field testing earlier this year one overwhelming piece of feedback customers shared with us was that they did not want us to provide the USB charger because “I already have plenty of USB chargers”. Our team took that feedback to heart and removed our version. We apologize that the lack of a USB charger effected your use of the device. We’d be happy to send you a USB charger at no expense. Please let me know if we can send that to you and further assist you. Thank you again for your feedback, and for choosing CO2Meter. -CO2Meter Team

      CO2 meter

      Nice little hand held meter for measuring C02. Will probably buy another for a different facility. Does everything and more that you could ask for

      Absolutely LOVE new model!

      I have to say that I absolutely love the new model. I feel it is more accurate than the previous model and I'm enjoying being able to read all the different measurements too, we really have no complaints at all! You will be seeing an influx of order in the not too distant future =)
