ProxiCube® NX3 uses a combination of highly responsive sensors to measure indoor air parameters that are important for our well-being and health. The ProxiCube® is the world's first product of its size to be equipped with the technology to measure the amount of liquid, respirable aerosols (liquid fine dust less than or equal to 2.5 μm / PM2.5) with a new BOSCH gas sensor in combination with fine dust sensors from Switzerland. The values are given in number of drops/cm3 and documented via cloud. The product is Made-in-Germany with patent pending technology by www.nevoox-europe.com.
