SM-4000 Personal Silica Monitor Kit

Orderable Items Silica Monitor SM-4000 is a direct-reading personal dust monitor optimized for the measurement of silica levels specified in the OSHA final silica rule. Calibrated to a known amount of silica dust, SM-4000 provides direct readings for determination of peak silica concentrations for mitigation and lower TWAs. The SM-4000 internal pump and gravimetric filter cassette (directly behind the sensor) provide for concurrent collection of a gravimetric sample for silica analysis and cross-calibration.

  • Low sensing range down to 1 µg/m3

  • High precision of ± 3 µg/m3

  • Readings display in µg/m3 — no conversions needed

  • Comes standard with GS-3 Cyclone that conforms to ISO 7708/CEN criteria

  • Concurrent filter sampling option for lab analysis and/or cross-calibration of displayed results
    • Gravimetric filter cassette located directly behind the sensor for maximum particle deposition
    • Internal pump flows at 2.75 L/min (user adjustable)

  • Sensor and filter cassette clip directly in the breathing zone

  • Datalogging
    • DustComm Pro Software allows for downloading, basic trend analysis, and graphical analysis and comprehensive graphical reporting
