Moisture meter PCE-RCM 11Air Quality Monitor for Indicative Measurement of Environmental Conditions \/ Determination of HCHO, particulate matter (PM2.5 \/ PM10) \/ Temperature and relative humidity \/ 3\" TFT LCD display The air quality monitor PCE-RCM 11 serves the indicative examination of environmental parameters. The air quality monitor enables the measurement of fine dust, temperature and relative humidity. The bright display of the air quality monitor provides information about the already mentioned parameters. Environmental monitoring can be done continuously with the Air Quality Monitor for up to five hours without the device being connected to a power source.","For permanent measurement, the air quality monitor can be connected to the mains via a USB interface. The rechargeable battery will be recharged within two hours if the air quality monitor is turned off. The display of the concentrations is further simplified by the use of a color rating scale, as this directly provides information about the air quality to the user.","In addition to the indicative measurement of formaldehyde, which can be harmful to health, there is also an orienting measurement of particulate matter pollution to be carried out. A distinction is made between particles with a maximum diameter of up to 10 μm (PM10) and particles up to a diameter of 2.5 μm (PM2.5).
