I do love a portable detector for monitoring when travelling, and I have a few. This one was exciting because of the additional features of humidity and temperature.In using, I found that it is difficult to see easily unless you're looking directly at it, so the viewing angle isn't that great. The other deal-breaker for this is the battery life, which just doesn't last as long as expected when not plugged in. About 20 hours at most means it would need to be charged daily. I didn't even get into testing for air quality because it is not a long-term solution for air monitoring for me. I have hand-helds that do the same thing that will last days at a time.

This carbon monoxide detector provides clear readings on an easy-to-read LCD. The added temperature and humidity monitoring are nice bonuses. The alarm is loud enough for alerts, though the accuracy may vary slightly. It is a good option for indoor air quality awareness.

Id Give it 0 Stars if i could. Total waste of money. I Held it next to the stove with the gas running to see if it would pick up any changes. Still showed 0 PPM. I held it behind my running cars muffler also showed 0 PPM. Trash.

Rating 2 STARS because I believe my unit is defective, or the technology just does not work. When I initially turn the Detector on it reads 15-20 ppm then it drops down to 0 after about a minute. If I turn it back off and on again the same thing happens. I have tested in a few different rooms and plugged in and in battery mode with the same results.We do use air filters in my house but I just don't believe that the entire house is at 0 ppm. If I am able to confirm with another detector I will update my review to 5 STARs.Overall the detector is a good value if it were to work. Other alarm type detectors cost more and provide less functionality. The benefit of those is that the batteries will last years. Because this has a nice bright screen that displays other information the battery lasts on the order of a day. This has not been an issue as we just plugged it into the wall.There is only 1 button that changes from C to F and it turns the unit off and on. I wish the screen brightness could be controlled. We are using this in a bedroom and at night this thing glows as bright as a night light. We turn it face down at night to avoid the bright light.

This is a very interesting device. (Nondispersive infrared sensor) (not dispersed through a prism or diffraction grating)I thought it would be the typical type of CO sensor, which is an electrochemical cell that reacts withCO and produces a voltage which is then measured and coverted to a PPM reading.Instead, this is an infra red absorption type sensor (spectrophotometer).It has an LED that makes a certain spectra of IR which is then consumed according to concentration of CO gas in the device. This is the first I have heard of this method being used on a small scale consumer device like this. Technology keeps moving.The advantages would be much faster response time than an electrochemical sensor, and chemical sensors have a definite life span beyond which they must be replaced, (much like a battery in that respect).As long as the LED and sensor remain functional, this may not suffer from that limitation.The one thing that is missing however, is a certification / testing stamp by an appropriate authority.For such a device, I believe that would b e The American National Standard Institute (ANSI) and Underwriters Laboratories (UL) standards ANSI/UL2075, ANSI/UL2017 .Not saying that it would not be in compliance. It probably is. Just that as a homeowner, there is no way of knowing about the device's efficacy / safety.I surmise that it uses this method also to measure the H2O in the air, and converts that to a humidity reading.Very cool technology. Offering better response speed, better longevity, etc.
