Real-Time Fiber Monitor for Asbestos Fiber Monitoring

Model 7400AD Real-Time Fiber Monitor

  • Detects presence of fibers in the air we breath including hazardous asbestos fiber and other fibers
  • Laboratory-calibrated for asbestos fibers according to NIOSH method 7400 (phase-contrast microscopy or PCM)
  • Simultaneously collects sample on standard filter for microscopic or chemical analysis
  • Visible and audible alarm when fiber concentration reaches user-defined levels
  • Field-portable and field-operable with rechargeable battery pack or AC

Model 7400 AD Description - Request a Quote

The Model 7400AD is a technologically advanced real-time fiber monitor that automatically detects and counts airborne fibers such as asbestos fibers, mineral wool, advanced composites, ceramic and glass. Each Real Time Fiber Monitor is factory-calibrated with traceability to NIOSH Method 7400 for asbestos fibers. The 7400AD ignores non-fibrous background particles using the proven principle of electric-field-induced fiber alignment and oscillation. The MSP 7400AD is the ideal instrument to measure airborne fiber concentration during asbestos remediation and removal operations. With its fully charged battery pack, the 7400AD will operate unattended for eight hours and record the observed fiber data at regular intervals. If the fiber concentration exceeds a user-defined, pre-set level, an audible alarm sounds.

Positioned ahead of the exhaust on the 7400AD fiber monitor is a filter from which one can obtain samples for later chemical or physical analysis, such as comparison with phase-contrast microscopy.

The on-board, user-friendly software allows you to set a range of performance features in support of your operation.
