The instrument has a built-in zero-adjustment filter, color touch screen operation, and one-button automatic zero-adjustment function, which can automatically calculate and directly display mg/m3.

This instrument can be equipped with Bluetooth printing function; it can increase the measurement function of hourly average and daily average.

This instrument can customize the measurement range.
