To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have a 2005 MDX SUV and few times suddenly I started to get dizzy and sleepy. One time even went off the road. I had never had such a thing happening to me for past thirty years of driving different cars to this extent. I suspected something must be in air or maybe food. I noted after meals I am more prone to it which is natural but then I ate and drove my EV Bolt car, no bad thing append! When it started also happening without any meals in my SUV , then I started researching and saw some officers had CO poisoning and their cars went off the road. So, I put a CO monitor but it picked up nothing due to lack of sensitivity. I finally came across this device and it was always zero, till one day that I started falling sleep. I stopped the car, opened the glove compartement that I had kept this and its number was seven. I opened the windows and by he time I took a picture of it, it had dropped to 6. So CO exposure in small amounts is causing the problem.
I bought this to check for CO in our Ford Explorer. This is a sturdy detector and has a professional feel and look to it. It's easy to use and carry around due to its compact size. Mine will read 0 most of the time and occasionally fluctuate to a 1 depending where im located. I wondered if it was truly reading anything, so I placed it near the exhaust of a running vehicle. Within a few seconds, it detected and displayed a reading of 5, and kept getting higher. I moved to fresh air, and it dropped back to 0. I'm impressed with the speed of the readings. Im hoping it's as accurate as it claims. I will update this review when it's time for its first calibration, or if I find something wrong in the meantime.
I leave this detector on 24/7 in my kitchen. We do a lot of cooking with a gas oven, and this device very accurately detects the carbon monoxide in the kitchen. It lets me know how much I should be ventilating my kitchen while we are cooking.
I clipped this device onto the stratux I carry on checkrides, and that way can keep an eye on the CO level of the many unfamiliar airplanes I fly in. I've tested it in my planes and used it to determine the effectiveness of the additional firewall sealing I've done. If you're an instructor or DPE who "speed dates" airplanes, it's a really good precaution to carry this device, especially during the winter months when cabin heaters are most likely to be used.
Wore this at work the first day (Fire Department) and when we were training with a power saw (gas powered) the alarm went off.....because we were being gassed and the reading went to 275!!!!! Now we know to take precautions.....Thank You!!!!!
This is a fast acting sensor, necessary for confined areas that may rapidly increase in CO. Think about your car with an exhaust leak, an airplane cabin, and so on. For anyone living, working, sitting in a confined area where CO can rapidly accumulate and result in death, this is a must have and no brainer.
The low level warning audible limit at 35ppm has tripped a few times in our small airplanes on descent. I'm able to hear that over my noise canceling headphones and the hum of the engine, although it does take a second to recognize what the alarm is. I haven't heard the upper limit trip yet.
I'm no expert on these; what I learned when researching this product is that the sensor in this and several other handheld devices are chemically based, and thus, need to be periodically calibrated and have the sensor replaced. Maybe future advancements will change the need for that in other devices. For now though, this satisfies my needs.
I've seen complaints on here that this works out to effectively $0.25/day for protection. But how much is your life worth? And do you buy life insurance? $1mm term for someone in their 40s is a little over $1.00 per day. That does nothing to ensure you are living, it simply provides a payout if they lose the gamble and you die. They pay your survivors, not you. This device helps to make sure you don't have to worry about that.
The device can be recalibrated and have sensors replaced by the manufacturer. The cost of that, and whether that's worth it to you or not, I can't speak to that. But for myself, I'll happily buy a new one of these every two years.
Living with an aging Natural Gas Furnace - I began to wonder whether or not the combustion gases and carbon monoxide were escaping into the heated room air. This can happen - over time - if the burner unit should rust through - after years of use. I could have had someone out to inspect my unit -- but since the inspector was also going to be the Salesman pushing a New System - I thought it wise to invest in this tool - and see for myself. It is easy to use and sensitive. I happened to have it with me when I dined in a small restaurant, and as the chef at the far end of the restaurant, lit the stove and began cooking my meal, I could see the unit register trace levels of carbon monoxide. When he shut it down, the numbers went back to zero. At home I was able to check my furnace, my water heater and units for a few friends. I am well satisfied with this purchase.
Small, rugged, visible alarm seems to work well in my airplane. Ability to lock in max reading is helpful Digital readout is important to me. I put the unit where I can see the face and if there is a CO alarm there are flashing led's in the four corners. It requires calibration every 6 months and unless we buy a calibration kit it has to be returned for cal. Either way adds to the cost. For our use, looking for CO spikes in the cockpit of a small plane, we don't need accurate calibration. The instructions imply that you can go 2 years and then another 180 days before you must get it calibrated. The cost of the unit isn't too bad, so spending a little for a cal every couple of years will be o.k. It would be nice if the unit had a backlight, but not critical.
Pretty neat device. It's easy to use, the countdown to shut it off is good to prevent it from accidentally being powered down. It seems to be accurate. One feature they should advertise more prominently is that this will operate non-stop on the battery for 2-4 years. It uses a CR123 battery which is only a few bucks to replace, so you might as well just leave it on all the time.
