Description
Product Details The 7400 is a technologically advanced real-time fiber monitor that detects and counts airborne fibers such as asbestos, mineral wool, advanced composites, ceramic and glass. The Real-Time Fiber Monitor is factory-calibrated with traceability to NIOSH Method 7400 for asbestos fibers. The 7400 largely ignores non-fibrous background particles using the proven principle of electric-field-induced fiber alignment and oscillation.
