APM-2 : Air Pollution Monitor
Product Descriptions
The method applied by the APM-2 uses the light scattered by tiny particles (nephelometry) to determine the PM10 or PM2.5 concentration in the ambient air directly and continuously. After performing a qualification test, TÜV Rheinland certified the procedure as equivalent to the customary gravimetric method. The device possesses an impactor inlet for fractionating the particulate matter, and a virtual impactor for dividing the air stream into two streams for the alternate determination of the fractions PM2.5 and PM10.
Design : The APM-2 consists of the following principal components
– Stainless steel cabinet
– Control unit with SD card reader
– Vacuum pump
– Intake tube
– Impactor inlet
– Virtual impactor
– Dispersion photometer
– Temperature and humidity sensors
– GPRS modem (optional)
