It does work.

This was tested against a very expensive co2 meter that I borrowed from a friend who works in confined spaces. It was very close there was 18 point difference. This was very affordable. The read out is not very high in contrast but it is readable. The temp and humidity levels appear to be accurate as well tested side by side my analog wall meter which I usually tap on. There is no backlight on this. The readout is equal to a large calculator. I am very happy with this purchase especially for what it cost. It is rechargeable so I don't have to purchase additional batteries.

Just what I needed for my CNC/Laser room

Something I bought that I badly needed for my detached CNC room. At times a lot of smoke is coming off my laser. Not only does it show the current CO2 level, it also shows the temperature of the CNC room. I can use my laser when it’s in the 40’s outside with my exhaust fan running for two hour bursts. Now, before I open the door. I can make sure all the CO2 fumes are flushed out. The CO2/Thermometer has a Bluetooth function. So I can monitor everything on my iPhone.I sit back in my bedroom and watch my CNC from a Geeni web camera. Now, I can wait until the CO2 level drops before I go back in the CNC room.To my surprise, the CO2 level actually dropped when I started using my laser with the exhaust fan running. My only concerns about the CO2 meter is that the screen is very faint. But I can view the levels on my iPhone.The CO2 meter does work well. I breathed on it for a minute or so. It showed the CO2 levels went up to a dangerous level.Setup: The instruction manual advised the app would connect Bluetooth to the CO2 meter. That did not work. However, I manually added the CO2 meter to the app using the QR code on the back of the CO2 meter. I set the time using the app, and many other functions.

For monitoring at home surely to be advised

ProSolid hardware versus priceDesignGreat display CO2 measurement, including traffic light barRechargeable battery (no permanent 220V connection)Long accu cycle timeEasy to programmContraNo alarm set point in instruction leafletBuzzer does not trigger when alarm is reached (hence 4 stars)Addition to review dated 16-03-‘24My message to Temtopus.com:Recently I received the Temtop type C1 CO2 monitor.At which CO2 level will the buzzer be triggered?No Info in the Instruction booklet about that. See picture.Answer Temtopus.comIf the CO2 level's changing from green to yellow, or changing yellow to red, it can both trigger buzzer alarm.My action after answer of Temtopus.com:Simulated testing, learned that indeed the buzzer is triggered at threshold levels. Two very short soft beeps can be heard.4 stars unchanged.Johan (from 'The Netherlands)

It gives me peace of mind.

It arrived packaged well and had the appearance of NOT being some cheap thing that would break soon. It was fully charged or appeared to be. The instructions are tiny but the first page has a QR code that I scanned and it pulled up the instructions on my phone. The information was helpful and I was outside calibrating it in just a few minutes. Calibration is done outside, away from pets and people and it takes 200 seconds. It also has a nice little stand with a metal bar on the top that the monitor latches when it is set on the stand and it sets up nicely and is easy to read. The monitor having a magnetic back can also be attached to a metal surface like a refrigerator for instance. In conclusion I run a propane heater at my fireplace in the winter and it may run for 12 hours at at a time. I have a few CO and explosive gas detectors throughout the house to alert me of dangerous conditons so that I don't wake up dead one morning from CO poisoning or get blown up from a propane gas explosion. The one thing I didn't know is how much CO2 was building up in the house from being closed up with a propane heater running so long each day. It gives me peace of mind to have the monitor but I really don't know how good it really is because I don't have anything to compare it to and I just started monitoring CO2 with it but I have to believe it will give me good information until I have reason not to.

Nice and works well. Perfect, You will like it.

Worls perfect for my needs. I liked it so well, I bought a second one. If you buy one, recalabrate it, Easy to do.If you are growing in a tent? You will need 2, (inside/outside) this way what is going on. I do like this CO2 meter and I will be buying another one soon.

Lack of backlight makes this a good choice for a bedroom

Most monitors have a backlight that can't be turned off. If you prefer to sleep in a darkened room, this is a good choice, with its basic unlighted LCD display. Also, without the backlight, the specs say its internal battery will keep it running for a month or two rather than the day or two which is typical for lighted units; this only matters if you need it to run for an extended period without being plugged in. It seems reasonably accurate; probably not a precision unit, but good enough to get a sense of your living environment.

Glitchy & Low Quality

The app is so glitchy. It doesn’t show historical data consistently and will skip dates when scrolling. The temperature takes a long time to update if you change from a hot to a cool location. Took it outside to calibrate for 2 minutes per instructions, then it took ages to show the accurate temperature once back inside. The screen is outdated technology. If you’re looking at it from the side the numbers are very faint even when charged.

It seems to be working well, was good on long airplane travel

So far the monitor works well, as expected. After calibration, I took it on an international trip to see how good the air was. The CO-2 was very high into the RED zone when boarding was in progress on the plane and for the first hour or so it was high, then dropped into the YELLOW zone and eventually into the HIGH GREEN zone where it stayed for about ⅓ of the flight.
