Continuous Particulate Monitor with X-ray Fluorescence



Continuous analysis of
particulate mass and the element
with automatic sampling.

 The first step towards prevention of air polluti
In recent years there has been growing concern regarding particulate matter (PM) pollution and its affects on health.
For effective preventative measures, source appointment of PM is extremely important. Therefore, indication of PM elemental concentration is
Newly developed PX-375 enables automatic sampling, continuous online PM quantitative and qualitative analysis and rapid air pollution source

Feature
1
Continuous analysis of PM mass and the elemental concentration
by a single unit directly in the field!
t Continuous analysis of PM2.5, PM10 or TSP, mass and the elemental concentration.
Sampling and the elemental analysis time are selectable.
t Extremely compact design – 19 inch size and easy installation enables the use of the
instrument in scientific laboratories, fixed and mobile air quality monitoring stations
(AQMS).
t Ideal for variety of applications: ambient air quality monitoring, indoor air quality control,
stationary pollution source appointment, etc.
t Continuous analysis provides you the benefits of reducing labor cost and human errors
caused by manual analysis.
