Introduction to the SKC EPAM-5000
Introduction The SKC EPAM-5000 is a high sensitivity real-time particulate monitor designed for ambient environmental and indoor air quality applications. This unit combines traditional filter techniques with real-time monitoring methods. These techniques combined overcome limitations of all other aerosol monitoring products.

Comparison of methods
Description of traditional method
Advantages of traditional method1
Description of real-time method
Advantages of real-time method1
The traditional and real-time dust monitoring methods are described below.
Air is drawn by a vacuum pump through a 47mm diameter membrane filter EPA FRM Style. The fibers and particles collected on the membrane filter must be counted or weighed in a laboratory for further analysis.
•EPA or OSHA compliance reference method.
•High level of specificity and accuracy.
•Collection of dust particles, which are available for further chemical analysis.
Dust particles are drawn into the sensor head and are detected once every second. Dust concentrations are instantaneously calculated and displayed on the SKC EPAM-5000’s LCD. All data points are stored in memory for later analysis.
•Immediate estimations of the concentration of a contaminant, permitting on-site evaluations.
•Provision of permanent 24-hour records of contaminant concentrations using continuous monitors.
•Internal audible alarm to warn workers of approaching hazardous situations.
•Reduction of number of manual filter tests.
•Reduction of number of laboratory analyses.
•Provision of more convincing evidence for presentation at hearings and litigation proceedings.
•Reduced cost of obtaining individual results.

Real-Time Dust Monitoring Principles
Principles • The SKC EPAM-5000 uses the principle of near-forward light scattering of an infrared radiation to immediately and continuously measure the concentration in mg/m3 of airborne dust particles.
•This principle utilizes an infrared light source positioned at a 90-degree angle from a photo detector.
•As the airborne particles enter the infrared beam, they scatter the light. The amount of light received by the photo detector is directly proportional to the aerosol concentration.
•A unique signal processes internally and compensates for noise and drift. This allows high resolution, low detection limits and excellent base line stability.
Figure 1.5. Diagram showing the principle of near-forward light scattering used in the SKC EPAM-5000.
