The Sper 900033 Particle Mass Concentration Detector is an advanced, desk or table top device that accurately monitors formaldehyde (H2CO) and other important air quality levels in a closed environment.

The large, colorful LCD display indicates multiple indoor air quality parameters with a thoughtfully designed, graphical user interface. The entire display functions as a six color warning system, where colors correspond to actual realtime pollutions levels.

The unit measures PM2.5/10 particle levels, as well as CO2 and TVOC (Total Volatile Organic Compounds) levels in the atmosphere. The system also displays relative humidity, temperature and date/time. The unit also features an internal memory that can record up to up to 5,000 datapoints to track PM2.5/PM10 readings over time. An integral fan draws air across the sensors for accurate monitoring, and features auto shutoff and "awake by sound" modes. The unit includes a rechargeable battery, USB cable and power adapter. 

Due to its toxicity and volatility, formaldehyde poses a significant danger to human health. Chronic (long term) exposure by inhalation as may happen from thermal or chemical decomposition of formaldehyde-based resins and the production of formaldehyde resulting from the combustion of a variety of organic compounds (for example, exhaust gases). As formaldehyde resins are used in many construction materials, it is one of the more common indoor air pollutants.

At concentrations above 0.1 ppm in air, formaldehyde can irritate the eyes and mucous membranes. Formaldehyde inhaled at this concentration may cause headaches, a burning sensation in the throat, and difficulty breathing, and can trigger or aggravate asthma symptoms.
