Sibata Quantitative Respirator Fit Tester MT-05C

The SIBATA Quantitative Respirator Fit Tester conforms to CSA Z94.4-11 and brings a collection of features and benefits never before seen in the Canadian marketplace.

​The SIBATA performs on any tight-fitting respirator (even N95’s!), including:

  • Disposable N/R/P Series, 95/99/100 masks
  • Half-masks
  • Full-facepieces
  • Gas masks
  • PAPRs
  • SCBA

The SIBATA is completely plug and play – just turn it on and you’re ready to go! Step-by-step guides on the full-colour display lead you through the latest CSA procedures for quantitative fit testing (QNFT).

All tests, including N95 and resusable respirators, are completed within the 3.5 minute CSA timings – the fastest in the industry!

Crafted from thin-gauge steel, the SIBATA Quantitative Respirator Fit Tester is designed to last. An integrated carrying handle makes it safe and easy to transport. The entire unit (including its handy mirror!) was made with wipe-down decontamination in mind, and weighs only 3kg (6.6lbs).

One Unit, Two Modes

Standalone Mode

The SIBATA Mask Tester Pro is a fully contained, out-of-the-box unit. Operated through the front touchscreen, the unit will guide the user through each exercise instruction and will display the results in real-time. Results will be logged and can easily be transferred to a computer later.

Computer Mode

Test results are transferred to your computer in real-time and are saved automatically at the end of each test. Both fit test reports and cards can then be printed as required.



Built to last, the SIBATA Mask Tester Pro is backed by a two year warranty. Canadian-based service and calibrations safeguards lower costs and provides a quicker turnaround, minimizing downtime. Since the unit’s particle counting technology requires no alcohol, operating expenses are minimized.


You’ve been fit tested, but are you entering a potentially high-hazard area? The SIBATA Mask Tester Pro has a ‘Fit Check’ mode that quantifies the respirators fit in real-time after you’ve donned your mask. A fit check guide is available that allows a disposable respirator to be checked for fit as part of a donning procedure.


The pump on the SIBATA Mask Tester Pro is extremely quiet and only runs during the tests. As a result, the subject enjoys a quieter fit testing experience, while the owner benefits from a longer lasting pump and less maintenance over the life of the instrument. The particle generator is also very quiet, contributing to a more positive fit testing experience.
