Model F – Portable CO₂ Sensor

Easy and non-intrusive means of monitoring air quality in public venues, often with surprising results that tell me which venues have good HVAC equipment and those that do not.

Looks great. I've used it on the Skytrain, bus and in healthcare visits in Vancouver to check air quality and see that I was glad I was wearing a mask, and others probably should be too. I wish the big button was at the 'lanyard' end of the device. When I'm holding it with the lanyard/carabiner towards me, my thumb reaches to touch the button and covers the screen. It'd be nice if the screen was visible. A small suggestion. I might make a protective cover for the detector because I'm afraid I'll damage it. Maybe with a bicycle inner tube, or leather or something. I'll send you a photo.

I purchased this to replace a Vitalight Mini CO2 monitor which I lost. I appreciate the slim form factor and the ability to download minute-by-minute readings for the past few days. Perhaps the most enjoyable aspect of purchasing this has been the responsive and personal service I received from the time I placed the order until I'd received it and had a few questions. It feels good supporting a venture that so clearly cares about what it is doing and strives to provide customers with an excellent product and outstanding support.

I take this everywhere in my backpack to help keep a close eye on air quality when I'm travelling. Very handy to have!
