SM-4000 Personal Silica Monitor
A Direct-Reading Personal Dust Monitor for the Measurement of Silica Levels
SKU
SM4000
The SKC SM-4000 Personal Silica Monitor is a direct-reading personal dust monitor that is ideal for the measurement of silica levels specified in the OSHA Final Silica Rule. It's light-weight design makes it ideal for active workers and the SM-4000 can withstand varying conditions.
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 also features a low sensing range down to 1 µg/m3 and a high precision of ± 3 µg/m3.
The internal pump and gravimetric filter cassette (directly behind the sensor) allow for the concurrent collection of a gravimetric sample for silica analysis and cross-calibration.
The SM-4000 Silica Monitor is ideal for perimeter monitoring of regulated areas with user-set alarms, task monitoring, recording time history of dust levels and more.
The SKC SM-4000 Personal Silica Monitor is available from Air-Met Scientific for rental only. For more information, contact your local Air-Met office.
