With its large, bright colour LCD display it is able to display all parameters of air quality in an easy to read intuitive display. The single button operation does away with cumbersome menus, and displays all the relevant information on one screen, while still having multiple display choices like graphs, simultaneous PM 2.5 and PM 10 readout and more.

The DT-969 also displays the Ambient temperature as well as the humidity. This gives the user a comprehensive insight into the quality of the surrounding air.
