Levenhuk Wezzer PLUS LP90 is a compact CO₂ monitor that can also measure air temperature and humidity. This small device alerts you if the CO₂ or humidity levels are considered too low or too high, making the inside area a less comfortable place to stay. If the concentration of carbon dioxide exceeds the recommended level for ventilated rooms, the gadget will alert you to air the room out. There are digital alerts on the color LCD screen and sound alerts available. If you prefer, you can turn the beeper off.

Another useful feature of the Levenhuk Wezzer PLUS LP90 CO₂ monitor is the history of maximum and minimum records. Furthermore, the device calculates the average CO₂ level every 15 minutes or 8 hours. It helps determine if there was enough oxygen in the room while you were sleeping. By regularly analyzing the obtained data and following ventilation recommendations, you can create a more comfortable atmosphere in any room, whether in a bedroom, children’s room, or an office.

The device is AC powered (an AC adapter must be purchased separately).
