Very good display visible from far away due to color illumination
It's a great little thing for the price. The accuracy seems to be quite ok, although according to the integrated sensor, the CO2 display takes up to 2 min to adjust to the correct value, since the air has to diffuse into the housing. However, this does not bother if you know it, you simply do not have to wonder why the display does not immediately jump from red to green when the window is open (already needs 1-2 min).
Compared to many other CO2 meters with partly tiny LED color display (green/yellow/red), it must be said that the beautifully colored but quite large screen is an enormous advantage to immediately see from afar how urgent it is to ventilate. The standard setting of the color gradient from green via yellow-green to yellow, orange, red, can also be used immediately and makes sense.
The only thing that bothers is the lack of an internal battery to store the time, as it would have to be set every time you unplug the device. I have never entered the time because of this - just use it as a CO2 device.
Connected to a mobile powerbank, the device works very well, and also amazingly long - up to a few days on one of my powerbanks, but also on smaller powerbanks but also for a whole day, whereby you can also use it mobile - you just have to think of the powerbank.
What also surprised me particularly positively is the possibility to connect the device to my laptop, and by means of a free software to record the measurements (see picture). The software is directly related to the built-in sensor ZG09, so it is possible, but it is not mentioned in the manual. Thanks to another review on Galaxus, however, I found out about it, for which I am very grateful. Great stuff!

- Luminous screen color depending on CO2 content
- Large display of CO2 content
- Relative humidity
- Temperature measurement
- Time history
- Mobility possible with small power bank
- Screen light can be adjusted if necessary
- With additional software time history on PC possible
Contra
- No internal battery, which could at least store the time etc.
- Setting the time not intuitive, but also hardly usable, since deleted as soon as plug is out
- Software for time history not mentioned in manual
Inexpensive, compact and mobile device with USB power supply.
Recommended for indoor use as a CO2 alarm. The display changes color from green to yellow to red, the threshold values can be defined by yourself. An acoustic signal is missing, but the display can change the color to red at a threshold value. For me a plus: With a connected power bank, the device can also be operated mobile. A plug-in power supply is missing in the scope of delivery, but it can be operated with any USB charger / power supply - or directly on the USB port of the PC.
The possible data output via USB is unfortunately not mentioned in the manual and the specifications. The device delivers the measurement data constantly via the USB port and
at ZyAura.com/support/support_software there is a suitable freeware for the data output under Windows XP to Windows11.
The measurement tolerance(*) is rather high (about +200ppm in the range of 2000ppm/-50ppm in the range of 500ppm) . However, the ranges around 800ppm to 1200ppm are precise enough to get a clear picture of the indoor air quality and also to make ventilation recommendations.
At low humidity aerosols remain longer in the air. The measurement and display of relative humidity is therefore an ideal functional addition.
*Since I lack a calibrated reference instrument, the comparison was made with an AirCo2ntrol Mini. Even the AirCo2ntrol Mini can output inaccurate values in the lower and upper ranges and so the deviation may also be due to this.
Conclusion: It is mobile, inexpensive and does what it should. Ideal for the office or for smaller occasions in closed rooms.Pro
- Display colour serves as a traffic light: green yellow red
- USB port as power source. Mobile operation with a powerbank possible.
- Measurement data transfer via USB (freeware application for Win XP-Win11 at zyaura.com/support)
- Also measures humidity
Contra
- Display backlight reduces readability at slightly sideways viewing angles
- Measurement deviations in the lower and upper measuring range. (sufficient for the statement of the air quality)
- Temperature display constantly approx. 1.5 degrees too high due to the heat generated by the display.
Super device for private use, name should be CO2 meter
Super device for private use, name should be CO2 meter
Pro
- plausible CO2 data
Contra
- no backup battery for short interruption
Great control of the CO2 content in the room
Pro
- Very good visual feedback on room air
- Also measures temperature
Contra
- Missing backup battery: time is gone as soon as power is gone
Does what it should (warning of too high CO2 content).
Nice device, in today's new buildings (without CO2-controlled ventilation) you sometimes stay too long in not healthy atmosphere, and this CO2 meter is a help.
Pro
- at a quick glance recognize when shock ventilation is needed
- in alarm mode it is inconspicuous, display off
Contra
- operating instructions not complete, after power failure it's a lucky thing to get back into alarm mode
Easy-to-read display, not only CO2, but also humidity protection
During the pandemic, we have equipped all flats in our apartment block with them to improve the air quality for our tenants. However, because a hygrometer is also included and therefore also indicates excessive humidity, we can now require tenants to air their flats regularly and briefly, as is correct (max. 5 minutes 4 times a day in winter). This saves us mould problems and the need for expensive comfort ventilation to prevent them. This also saves grey energy...
Pro
- Easy to connect
- hardly needs any instruction
Contra
- moderate quality and durability
Ok
Hm, how accurate are the other values?
Contra
- Humidity display is not correct, shows about 15 too little
actually unusable
According to the description, the maximum deviation for air quality should be ±7 % or ±100ppm, for humidity ±3 %.
Unfortunately, I trusted the brand "TFA" unchecked and disposed of the packaging, otherwise I would have sent the device back.
At Aliexpress you can get five to ten such devices for the same money as the TFA device, which are approximately equally "accurate".Pro
- Temperature display correct
Contra
- Air quality indicator too low by about15 % (150 - 120 ppm)
- Humidity display 15% too low
It can do something, but...
It is a top device for keeping an eye on the carbon dioxide content in the room air. The bar display, which is saved approximately every three hours, is a great way of showing the progress over the past twenty-four hours. Unfortunately, all these values are lost at once when the unit is disconnected from the mains. This also applies to the time, which is rather complicated to programme. In my humble opinion, its implementation on the display could have been done without.

No problem, only ale visitors are more nervous about the ads.
Since small, the device can also be placed discreetly.

Ok but runs only with electrical connection

Contra
- No battery or accumulator operation possible
Useless as a mobile device
The year is 2021, yes, that's 2001 years after Jesus and more than 200 years after the invention of the battery. Only the manufacturer of this device has never heard of batteries, let alone rechargeable batteries. This device is only suitable for fixed mounting and fixed power supply. There is no question of mobility. Ok you can carry it around but not use it. I don't know what IQ the designer of this device had.
Pro
- nothing
Good
Pro
- Very informative, easy to use
Contra
- No backup battery, no battery operation possible
