The Sibata MT-05C Respirator Fit Tester is completely plug-and-play – just turn it on and you’re ready to fit test. Step-by-step guides on the full colour display lead you through the latest CSA procedures for QNFT.


All tests (including N95s and reusable respirators) are completed within the 3.5 minute CSA timings. This allows for more tests in shorter time – which means less down time for you!


Crafted from thin-gauge steel, the Sibata MT-05C  is built to last. An integrated carrying handle makes it safe and easy to transport. The entire unit (including mirror) was designed with wipe-down decontamination in mind, and weighs only 3.0 kg (6.6 lbs).


The Sibata MT-05C Respirator Fit Tester performs on any tight-fitting respirator, including N95s:

  • Disposable N, R, P Series 95, 99 or 100 HEPA masks
  • Half-masks
  • Full-facepieces
  • Gas masks
  • Powered air-purifying respirators (PAPRs)
  • Self-contained breathing apparatuses (SCBAs)

Operating Modes

The Sibata MT-05Coffers two (2) modes of operation. Both can be used in standalone mode, or when connected to a PC, using Sibata’s patented software.

95 Mode

The 95 mode is best suited for testing disposable respirators with a filter efficiency of 95%, including N95, R95, P95 filtering facepiece respirators and elastomeric respirators with N95, R95, and P95 filters attached.

99+ Mode

Ideal for fit testing half mask respirators, full facepieces, SCBA, and filtering facepiece respirators with 99 or 100 rated filters. The 99+ mode can also be used for any other respirator that has a filter efficiency of 99% or greater. This includes N, R, and P rated filtering facepiece respirators, and half mask, full facepiece, and SCBA respirators.
