PM2.5 High Volume Air Sampler
The Tisch Environmental PM2.5 high volume air sampler is a non-Federal Reference Method sampler
for the collection of particulate matter that is 2.5µm or less. Its primary uses is for non regulatory
sampling and institutional studies. The PM2.5 size selective inlet is made up of 40 stainless steel
nozzles that allow only 2.5µm particulates to get deposited on the filter. PM2.5 particulates are
particularly hazardous to your health as they can work their way into your lungs during respiration
and can be absorbed into the bloodstream.
The PM2.5 high volume air sampler collects particulates at a flow rate between 36-60 cfm through a
PM2.5 size selective inlet. As the particulates travel through the size selective inlet the larger
particulates are trapped inside of the inlet as the smaller PM2.5 particulates continue to travel
through the PM2.5 inlet and are collected on the 8″ x 10″ quartz filter paper. This quartz filter is
weighed previously to sampling and after the sampling to determine the mass of particulates that
are smaller than 2.5 microns. The flow rate on this instrument is controlled by either a mass flow
controller, a volumetric flow controller or the Tisch Environmental PLUS technology electronic flow
controller. Tisch Environmental offers a wide range of PM2.5 samplers with several different
options to fit every custom sampling installation.
Key Features
Mass Flow Controlled
Mass flow Controlled or MFC PM2.5 particulate samplers use a hot wire anemometer probe to
control the flow rate. The hot wire anemometer probe is inserted into the flow stream and
automatically adjusts the motor speed as the filter begins to collect particulate. These systems are
available with either a 7 day mechanical timer or a US EPA recommended digital timer to ensure
accurate sampling results. Motor options include your choice of a brush style motor or a brushless
style motor. Please review the chart below to view our extensive offering of mass flow controlled
PM10 high volume air samplers.
Volumetric Flow Controlled
Volumetric flow controlled (VFC) PM2.5 particulate samplers use a critical orifice with a
predetermined orifice hole diameter to control the flow rate. The critical orifice is drilled and
calibrated to let only the predetermined flow rate to pass thorough the filter. The motor on these
systems operate wide open while the critical orifice maintains a constant flow rate. These systems
are available with a 7 day mechanical timer or a US EPA recommended digital timer. These systems
can be fitted with an economical brush style motor or a maintenance free brushless motor.
PM2.5 PLUS Controller
The PM2.5 PLUS system is the most advanced TSP ambient particulate sampler on the market. It
utilizes a microprocessor based controller to for instantaneous and accurate flow control. The
systems built in temperature and barometric pressure sensors along with the microprocessor based
mass flow controller allow the system to accurately calculate the flow rate. The PLUS technology
flow controllers include a built in digital timer with internal battery backup, multiple elapsed time
indicators, and four data logs with an external USB drive for data retrieval. The system data logs
record the average, minimum, and maximum ambient temperature and barometric pressure as well
as the total ambient and standard flow rate. These PLUS technology flow controllers also include an
auto calibration feature which eliminates the need for lengthy field calibration and manual flow rate
calculations.
