Portable CO2 Meter Handheld CO2 Detector Monitor 0~9999ppm Product arrived quickly and was brand new. I put in the 4 batteries and hit the top left start button, and it fired right up. This CO2 detector is a game changer. I thought the office had a Carbon Monoxide problem. After buying a expensive CO detector [everyone should have a CO detector of some type] I found out with this device it was CO2 that was the problem. The room was running at 800 ppm to 900 ppm and thats when a absolute brain fog would hit. We ended opening up some windows limiting the use of the gas stove and brought in fans for circulation. The PPM is now about 500 ppm sometimes around 430 ppm which is a huge difference. I have not messed with any of the setting so far no need to. Overall excellent product! If you are having a brain fog or feel a little strange and lethargic in the house/room or office it may be high CO2 levels. This device will help determine if that is the issue, and hopefully help you solve it.

Compré el producto para medir CO2 de manera continua en el laboratorio, sin embargo no pude conseguir el software y cables adicionales. Tuve que comprar otro equipo de otra marca.

We have had to use this product two or three times since purchase and it has works exactly as advertised. Gave us readings and action to take accordingly. Easily portable which is nice as well. Don’t charge a battery in a closed space or leave a bucket of hot ashes in your house.
