Real-Time, asbestos Fiber Monitor

MSP Corporation, Model 7400AD, Real-Time Fiber Monitor

  • Detects presence of asbestos fibers and other fibers in the air we breath
  • 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 Power

Model 7400 AD Asbestos Fiber Monitor, 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 asbestos fiber monitor, M7400AD, 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.
