ExtechEA80 Easy View Indoor Air Quality Meter/Datalogger

Es una excelente marca de confianza para este detector de CO2, con números muy grandes y perfectamente legibles a una distancia larga.No tiene pantalla iluminada y es sencillo de manejar (vienen las instrucciones en español). Con indicación de temperatura (tanto en grados centígrados como en celsius), humedad, hora y datos de calendario.Hay que tener en cuenta que la unidad viene sin batería que pueda hacerlo inalámbrico (aunque lo dice en el anuncio) y simplemente funciona con la conexión de la unidad a la red eléctrica de casa. No es portable en este sentido.

I bought this item because i was having some challenges at work. By 8:30 am.. my brain will be out of oxygen, and will feel dizzy and ready to pass out.I though it was CO. At the end i could not figured why i was sick..I still use this monitor in my home. If i am working in my office, by 2:00 pm.. they monitor starts beeping, the carbon levels are more than 1000 - the recommended value by EPA. I open the windows and let the fresh air in, and the values go down to around 500.I think most of us do not realize how much CO accumulates is in your home when the windows are closed or a lot of people are in close spaces. My nephews were playing in my office and maybe within 45 minutes the monitor started beeping. 2 people created high CO levels. mm.

seems to do what it is supposed to.

Ihe logger is always connected to the plug and must be placed on a desk. Take care of the snoring and use a cable binder to make it stabel when people are walking around.

Great Product!!!
