What's the use case? Ie what could cause a high concentration of CO in your house?
Old, faulty, or poorly installed gas appliances, stoves, hot water heaters, would probably be the main culprit.. also wood heaters…
During winter we user gas heaters in the house - they burn oxygen and if left on in a non-ventilated room, would be detrimental to your health. I think this will help in that situation.
detrimental can include death.
snow camping with a gas heater in the tent
From memory a Perth family died in Dec 19 as they kept their LPG camping fridge inside their tent at night…. Never woke up

Heres another instance, it does happen unfortunately :(
If I didn't already have the Google Nest wireless Smoke & Carbon Monoxide Alarm in my bus, would grab one in a heartbeat.
Bus?
Bus? Campervan? Motorhome? It's a 1998 Toyota Coaster SWB converted to a mobile war room for working/camping/living off grid.
Nice!👍
cool. real wheel drive? how many people live in it? how much did you spend?
@bargain huntress: Landcruiser 1HZ engine, rear wheel drive.
Purchased for $7,500 a few months ago, still fitting it out. Need to find some time to get more into it on the weekends. Expect to spend around $15k on the total fit out by the end of it.
Will be fairly standard build - shower, kitchen, 3way fridge, freshwater tanks, solar. Using a zero breeze mark II in the setup to cool the thing without having to run an engine (200ah 24v agm).
I've kept 4 seats (Driver, passenger, 2 immediately behind the drivers seat setup as a work area. Sleep 2 to begin with (where there is a small couch will be used as cot/bunk in the future).
And enough room for the parrot cage and 3 doggos.
just remember CO is nearly the same density as air, so the ideal mounting position is where your nose is.
so if you're lying in bed, ideal height is the height your nose is off the ground and so onOh I thought they should be mounted low ?

Contrary to a significant amount of public opinion, CO did not layer on the floor, float at the middle of the chamber, or rise to the top. In each case, the levels of CO equalized throughout the test chamber. It took longer to equalize when CO was infused at the top of the chamber than the bottom, but levels always became identical with time.
Conclusions
As would have been predicted by the Second Law of Thermodynamics, CO infused anywhere within the chamber diffused until it was of equal concentration throughout. Mixing would be even faster in the home environment, with drafts due to motion or temperature. It would be reasonable to place a residential CO alarm at any height within the room.
Probably confused with CO2 which does "sink" in air, as our high school chemistry experiments with glowing splints taught us.
very interesting, thank you. I had it low near the floor cuz that's what i was always told that LPG Gas / CO sinks all the way down! clearly i've been doing it wrong, i will remove the alarm and place it on a higher level
Does anyone knows how it compares to the one at Aldi?
https://www.aldi.com.au/en/special-buys/special-buys-sat-13-…
They're probably the same. They look identical other than branding. Aldi one is also $5 cheaper.
Even if you already have one outside at living room/kitchen/etc, for peace of mind I'd still put one installed in each bedroom, as that's when you really at the most risk - sleeping and not aware you're inhaling gas.
Any idea of these cheaper alternatives work?
How do you test them?
https://www.amazon.com.au/dp/B088RDSLB6/ref=cm_sw_r_cp_apa_f…
I've tested other yum cha ones that look very similar. They alarm way too high
PS: I sell commercial gas detection for a living.
Think underground car parks, labs, IVF etcThey alarm way too high
As in their trip point is set too high as part of their design or that do not trigger when they should because the sensors are unreliable / lose cal / something else?
(Also, what are you measuring in IVF? )
Bit of both as they are semi conductor cells which inherently are not for accuracy, they are more for yes/no applications.
The one in the OP is electro chemical. This is the best.
In IVF it's oxygen depletion from the liquid N2 fridges and dewars
The one in the OP is electro chemical
I'm not so sure. I too work in the gas sensing industry, and CO electrochemical cells don't have anywhere near a 10-year operational lifetime, as stated on the package.
Quote: "Electrochemical sensors for common gases such as carbon monoxide or hydrogen sulphide have an operational life typically stated at 2-3 years. "
https://www.hazardexonthenet.net/article/128977/Understandin…The datasheet for the sensor does say "Smoke Sensor Electrochemical", but this is NOT a smoke sensor, it's a CO sensor.
Quote: "CO alarms only detect CO gas. They do not detect smoke, fire, or other types of gas."
https://esv.vic.gov.au/gas-technical-information-sheets/36-c…I'm inclined to believe that the datasheet was copy-pasted from their smoke alarm datasheets, and I don't trust anything it says.
@Russ: I have seen 10yr ones but not at this price point.
Think that info might be out of date, our sensors easily last 5-6yrs
Thanks. Very informative
If you already have one, check the date on it. These are good for 10 years then it should be replaced.
Yes critical as they will fill unsafe.
They lose sensitivity like a battery.
So the same ppm of gas will be detected as less once old
I have one of these, seems to be doing the job. I'm still alive to be telling the tale
Or it doesn't work and you just don't have any gas leaks?
Do you have a manual way to test it? I don't trust the test buttons on these things
Smouldering cardboard, incense stick, cigarette smoke all have CO.
Just give it a quick wave near the sensor to test
Can't stress enough how important these are!
