The air quality meter displays measurements on a brilliant color screen. The fine dust particles measured by the PCE-RCM 10 air quality meter are in the PM 2.5 range, which can penetrate the lungs, settle there, and cause damage. This air quality meter is very suitable for preliminary measurements in potentially dust-laden workplaces. The measurement values are shown on the color display in a gradient from green to yellow, red, and pink. This traffic light function of the air quality meter makes it easy to recognize the limit values and allows for a quick response to changes. With the graphical measurement display setting, you can observe measurement changes over a period of 3 minutes. Additionally, the current temperature and relative humidity are displayed. The air quality meter can be powered by the built-in battery or via the USB port. The USB port is also used for charging the battery.
