With the PC220 you have a versatile mobile environmental measuring device. It can be used to simultaneously detect not only the particle purity of the indoor air on six different size channels from 0.3 m to 10 m, but also gas concentrations of formaldehyde and carbon monoxide. It can further be deployed for determining climate data such as the air temperature, humidity, dew point temperature and wet-bulb temperature.
Moreover, due to the fact that the measuring device displays the particle masses directly as mass proportion in g per m of air, the PC220 is suitable for a quantitative determination of the concentration of airborne inhabitable dust (PM10) and alveolar dust (PM2.5).
The standard equipment of this ISO-21501-4 compliant laser particle counter also includes an installed digital camera for documenting the measuring environment by means of photos and videos. The measurement data, date and time are also saved and indicated in both photos and videos to elucidate the measuring site.
The PC220 also comes with an integrated data logging function for non-stop measurements: up to 5,000 measurement records can be saved directly on the internal memory which can be expanded additionally by up to 16 GB using a MicroSD card. After measuring, all detected data can be transmitted quickly and easily to a PC for the purpose of documentation or analysis via a USB interface.
Key functions:
Integrated HCHO detector ideal to analyse the risk posed by formaldehyde
Methanal also known as formaldehyde is the chemical precursor for many industrial products ranging from varnishes or paints to adhesives and binding agents, even preservatives. Many materials containing formaldehyde, e.g. wood-based materials, flooring or textiles, can contaminate the breathing air in closed rooms for a long time through out gassing.
Reclassified as carcinogenic
Owing to its particular toxicity the responsible organization in Germany adopted a new maximum allowable concentration (MAC) for formaldehyde; at the same time the substance was classified as carcinogenic in the European Chemicals Directive (CLP). This necessitates certain precautionary and protective measures. The reclassification is effective as of 01/01/2016 and entails new duties of documentation and information for employers such as the obligation to keep an exposure register.
PC220 for the precise detection of formaldehyde
The particle counter PC220 comes with an integrated HCHO detector which reliably detects formaldehyde concentrations of as low as 0.01 ppm in the room air.
Combined with the additional CO detector, the quantitative particle mass display conforming to PM standard and many further measuring functions for particle purity and room climate data, the PC220 is the ideal solution for detecting and documenting formaldehyde concentrations in the room air.
Quantitative detection of particulate emissions
Quantitative statements regarding the particulate emission ratio for the assessment of potential health risks at the workplace are not only required according to applicable legal protective regulations.
To be measured are not only inhalable dust fractions, i.e. all dust particles with an aerodynamic diameter of less than 10 m, but especially ultrafine alveolar particles, which are so minute that they can reach the pulmonary alveoli.
With the PC220 these dust fractions can be registered as PM10 and PM2.5 according to the PM standard; their percentage per cubic metre room air is indicated numerically on the colour display of the PC220.
The process is based on the customary international PM classification in categories as per United States Environmental Protection Agency: air particles are differentiated by their aerodynamic diameter of less than 10 micrometres (PM10) and 2.5 micrometres (PM2.5).
