Chapter 1 Introduction to the SM-4000
Chapter Overview
The SM-4000 Real-Time Silica Personal Monitor is a modified version of the HazDust
model HD-1004. The SM-4000 comes complete with respirable cyclone and calibrated to correlate readings
to ISO 12103-1 A2 Fine Test Dust in ug/m³ (micro grams per cubic meter).
The SM-4000 combines
traditional filter techniques with real-time monitoring methods. These techniques are combined to
overcome limitations found with other manufacturers’ real-time particulate monitoring products. The SM-
4000 can be cross calibrated to OSHA’s new ruling using the 37mm filter cassette, mounted in the OSHA
defined breathing zone and the unique scaling and correction factor features found in the SM-4000 software
can be used.
