Continuous elemental and particulate mass analysis with automatic sampling
There has been a growing concern regarding particulate matter (PM) pollution and its effects on health. For effective preventative measures, the determination of source PM concentration is extremely important. Therefore, indication of PM and elemental concentrations is critical. The PX-375 analyzer employs automatic sampling, continuous on-line PM quantitative and qualitative analysis for rapid air pollution measurements.
- Continuous analysis of PM mass and the elemental concentration by a single unit directly in the field.
- Adoption of world proven technologies: X-ray fluorescence & Beta-ray attenuation.
- HORIBA’s filter tape provides excellent sensitivity and precise performance
- Installed CMOS camera enables observation of collected particulate sample on the filter.
- User friendly display and operations
