TSI PortaCount Pro+ Model 8038 Quantitative Fit Tester

Overview

The TSI PortaCount Pro+ Model 8038 is a portable, quantitative respirator fit testing instrument engineered for precision, regulatory compliance, and field-deployable operation. It employs condensation particle counting (CPC)-enhanced light scattering technology to directly measure airborne particle concentration inside and outside a respirator in real time. By comparing these two concentrations, the device calculates a quantitative fit factor (FF) — a dimensionless ratio that objectively quantifies the seal integrity between the respirator and the wearer’s face. Unlike qualitative methods (e.g., saccharin or irritant smoke tests), which rely on subjective sensory response and carry high false-negative risk, the PortaCount Pro+ delivers traceable, repeatable, and auditable numerical results aligned with OSHA 29 CFR 1910.134 and ANSI/ASSP Z88.10-2019 standards. Its core architecture is optimized for workplace respiratory protection programs requiring documented, defensible fit verification across diverse respirator types — including filtering facepiece respirators (FFRs) such as N95, P2, and P1 masks; elastomeric half- and full-facepiece respirators; powered air-purifying respirators (PAPRs); and self-contained breathing apparatus (SCBAs).

Key Features

• Real-time quantitative fit factor calculation with measurement range up to >10,000 FF in under 60 seconds — validated for all respirator classes per OSHA Appendix A.
• Integrated N95 Companion™ mode reduces standard N95 fit test duration from 10:24 to 7:15 minutes while maintaining statistical robustness and regulatory acceptability.
• Standalone operation enabled by built-in color touchscreen interface — no external PC required during test execution.
• Field-rugged design with battery-powered portability (up to 8 hours continuous operation) and IP54-rated enclosure for industrial environments.
• Enhanced low-concentration sensitivity allows valid testing even in ambient particle environments as low as 100 particles/cm³ — critical for cleanroom or low-dust facilities.
• Automatic protocol sequencing per OSHA-required exercises (normal breathing, deep breathing, turning head side-to-side, moving head up-and-down, talking, bending over, normal breathing) with visual and audible prompts.

Sample Compatibility & Compliance

The PortaCount Pro+ Model 8038 is validated for use with all NIOSH-certified respirators, including disposable FFRs (N95, KN95, P2, FFP2), reusable elastomerics, PAPRs, and SCBAs. It meets the technical performance criteria specified in OSHA 29 CFR 1910.134 Appendix A (Quantitative Fit Testing Protocols) and is recognized by NIOSH as a Type C quantitative fit testing instrument. The system supports GLP/GMP-aligned data integrity through secure user authentication, electronic signature capability, and audit-trail-enabled test records compliant with FDA 21 CFR Part 11 requirements when used with FitPro™ software. All calibration and verification procedures follow TSI’s documented metrological traceability to NIST standards.

Software & Data Management

FitPro™ software (v5.0+) provides centralized management of fit test protocols, subject databases, respirator libraries, and regulatory reporting. It automates pass/fail determination based on OSHA-mandated minimum fit factors (e.g., FF ≥ 100 for N95s, FF ≥ 500 for half-mask elastomerics). Test reports include timestamped raw particle counts, calculated fit factors per exercise, summary statistics, and digital signatures — exportable in PDF, CSV, and XML formats for integration into enterprise EHS platforms. The software maintains immutable audit logs recording operator actions, configuration changes, and calibration events — essential for internal audits and regulatory inspections.

Applications

• Occupational health departments conducting mandatory annual or baseline respirator fit testing per OSHA, MSHA, or provincial occupational health regulations.
• Hospital infection control units validating N95 fit for healthcare workers during pandemic preparedness or routine PPE compliance programs.
• Pharmaceutical and biotech manufacturing sites requiring GMP-compliant respiratory protection validation under ISO 14644-1 controlled environments.
• Fire departments and hazardous materials response teams performing SCBA fit verification under NFPA 1500 and NFPA 1981 standards.
• Industrial hygiene consultants delivering third-party fit testing services with legally defensible documentation.

FAQ

Does the PortaCount Pro+ Model 8038 require annual recalibration?
Yes — TSI recommends annual factory recalibration using NIST-traceable aerosol generators and reference CPCs to maintain measurement accuracy within ±10% of reading. Field verification using TSI’s supplied challenge aerosol and zero-air check should be performed before each day’s testing session.

Can it be used for testing respirators in cleanrooms?
Yes — its enhanced low-background sensitivity enables reliable fit testing in particle-controlled environments where ambient concentrations fall below 200 particles/cm³, provided the challenge aerosol concentration is maintained at ≥50,000 particles/cm³ per OSHA protocol.

Is FitPro™ software compatible with Windows 11 and networked database systems?
Yes — FitPro™ v5.3+ supports Windows 10/11 64-bit OS and offers optional SQL Server backend deployment for multi-site enterprise data consolidation and role-based access control.

Does the device store test data internally if the PC is unavailable?
No — the Model 8038 does not retain test records onboard. All data must be captured in real time via USB connection to a host PC running FitPro™ or exported post-test via microSD card (optional accessory).
