Particle Counter PC220

The PC220 is an ergo­nomic, hand-held measuring device with a built-in photo and video func­tion, which allows the user to monitor air par­ticles and gather environ­mental data directly on the spot.

With its ISO 21501-4 conformity, the PC220 can be used for various measuring functions from testing cleanrooms and filter efficiency to monitoring burdens at workspaces and quality assurance.

All measured values of the six particle size channels are shown simultaneously on the 2.8 inch colour LCD display.

An additional colour indicator display with automatic acoustic alarm makes it easier to quickly detect critical particle concentrations.

Besides the size and amount fractions of air particles the PC220 also detects environmental factors such as air humidity,air, dew and wet-bult temperature.

Moreover the particle counter PC220 has a built-in HCHO detector, which can measure the formaldehyde concentration in the room air from 0,01 ppm.

The particle counter PC220 enables the quantitative assessment of particulate emissions with an aerodynamic diameter smaller than 10 μm (E-dust) and 2,5 μm (A-dust). The dust fractions are measured and their parts per cubic meter of room air (μg/m³) are indicated on the colour display.

The photo and video documentation of measuring environment takes place by means of a bulit-in digital camera. The PC220 data logging function can store up to 5,000 measurement records on its internal memory. This can be expanded by up to 16 GB with a MicroSD card, which significantly raises the storage capacity. After measuring, all detected data can be quickly and easily transmitted to a PC via a USB interface for documentation or analysis.
