With the Levenhuk Wezzer Air PRO DM40 Air Quality Monitor, life in the big city can be improved. The air in large cities is usually full of harmful emissions from construction sites, cars, machinery, and industrial plants. They all emit tons of tiny particles into the air we breathe. Settling in our lungs, they cause allergies, bronchitis, and asthma. You cannot avoid it but you can keep it under control by monitoring the level of harmful pollutants in the air. This is where the Levenhuk Wezzer Air PRO DM40 can help.

The first important feature of the device is to measure the level of fine particles. The monitor can detect medium, small, and very tiny particles (PM10, PM2.5, and PM1.0). The second feature is a CO2 monitor. The concentration of carbon dioxide significantly increases in unventilated rooms, which leads to a deterioration of your health and performance. The gadget will alert you to situations where the CO2 level becomes critically dangerous to your health.

The device has two additional features for microclimate evaluation: a thermometer and hygrometer. There is also a clock and calendar. All of the information is clearly displayed on the screen, and there is a backlight. A rechargeable battery is used to power the device.

Please note: An AC adapter (not included) is required to charge the device. The USB port voltage of the PC is not sufficient for this purpose. You can also use a smartphone charger.
