WISUALARM M1 CO2 Air Quality Monitor
Please read this manual carefully before using the product and keep it properly.
What is carbon dioxide (CO,)
Carbon dioxide (CO) is a colorless, odorless gas that is produced by metabolic processes, combustion processes, and motor cars operating in garages. People and other animals exhale carbon dioxide when they breathe. Although carbon dioxide alone is not dangerous, the quantity found inside is utilized as a gauge for human comfort. The majority of the time, CO2 poses a health risk when its concentration is high enough to displace oxygen and cause suffocating in small spaces.
What are the effect of exposure under high-level carbon dioxide?
In buildings with increased CO OCcupants may have health problems. The carbon dioxide itself can produce headaches, lightheadedness, nausea, and other symptoms at high concentrations. This could happen after many hours of exposure to levels higher than 5,000 ppm. Exposure to CO, concentrations about 40,000 ppm is instantly hazardous to life and health since it can asphyxiate at much greater levels by replacing oxygen in the blood.
What should I do if the Air Quality Monitor goes off?
When the carbon dioxide concentration reaches a high level, the product will emit an audible signal and red LED goes on. For your safety, please ventilate your rooms:
- Open doors and windows
- Turn on mechanical ventilation system such as HVAC system
Product Introduction
- The product can monitor indoor temperature, humidity, and CO, concentration to easily master indoor air quality.
- The 4.2-inch extra-large E-ink screen is used as the display screen, which can provide a paper-like display texture and a clear multi-view angle.
Attention: Please avoid blocking the vent hole when using the monitor.
Accessories
Note: The illustrations of products, accessories, user interface, etc. in the manual are schematic diagrams for reference only. Due to product updates and upgrades, the actual products may be slightly different from the schematic diagrams. Please refer to the actual products.

How to use
Before use
Please charge the monitor before the first use. At the same time, turn on the monitor and vetilate for more than 24 hours. There is no need to operate the monitor during ventilation. Remove the pollutants (if any) on the sensor from the package or the interfering gases. Meanwhile, the product will be self- calibrated to ensure the accuracy of subsequent measurements. When testing, please place the product upright on the object platform where testing is performed, such as the desk or workbench. Please avoid holding the tester or blocking the vent hole.
Daily monitoring
- Turn on the monitor
- Press the power button for 3 seconds to turn on the monitor.
- Start monitoring
- After warming up for 5 minutes, the monitor enters the monitoring mode, and the screen displays the CO; value detected in real time. At this time, user could take the monitor on the place to be monitored for about 5 minutes, then read the current value through the screen.
- Turn off the monitor
- In the monitoring mode, press the power button for 3 seconds to turn off the monitor.
- Charging
- This product uses a lithium battery for power supply. When the low battery symbol °is displayed on the screen, it indicates that the monitor has low power and needs to be charged. Please insert the charging cable’s USB Type-C connector into the charging port on the back of the monitor and USB Type-A connector into the power adapter for charging. The product can be fully charged about 6 hours after being connected to the power supply.
- Note: Please use a 5V USB power supply for charging and ensure that the output current is greater than 1A. If the monitor is not used for a long time, please charge it regularly. It is recommended to charge it at least every 3 months.
- Restore default settings
- Long press the power button (hold for at least 16 seconds) until the monitor refresh screen, then restart the monitor to restore the default settings.
