Purchased one of these for my office. Worried the CO2 level was too high, suprised to discover it was too low! The outsde air damper in the building was stuck open, so we were running the furnace 24/7. Fixed it and the utility bill dropped. Neat! Indoor Air Quality Meter - CO2, Temperature, Realitive Humidity
This unit seems to be working very well. The response of CO2 readings is very fast. One undesired feature is that it flashes light (from inside). It's a very small light and may be easily covered up, but still it is not a good feature if someone wants a total darkness for some periods of time. Among 3 humidity meters that I tested it gives the highest reading (at least 5% higher than the others), but may be the other 2 are wrong (one is built in a dehumidifier, and another an inexpensive digital device).
Every family alreay has a temporature/humidity meter, costing $10. So this product only gives you a CO2 function, but even this function overlaps with Smoke/Carbon-Minoxide detector. Therefore the CO2 meter has minimal add-on usage. The price [...] is a joke. [...] price may attract a hobby scientist like me to buy. - Air Quality'
