Indoor Air Quality Meters

When you need answers now, handheld IAQ meters are the fastest path to actionable insight. In manufacturing spaces they serve as the multi-tool for commissioning crews, maintenance techs, process engineers, and EHS teams. TSI handheld instruments combine trusted sensing performance with practical ergonomics, giving you the flexibility to investigate, verify, and document indoor air conditions anywhere on site.

Use cases include:

• Ventilation verification at workstations and along production lines.
• Troubleshooting quality concerns near coating, soldering, or adhesive application.
• Comparing baseline to post-maintenance conditions after filter changes or system balancing.
• Walkthrough assessments in warehouses, maintenance shops, and shared spaces.
• Quick checks to validate the impact of process changes or temporary barriers.

Measurements that matter:

• Particulate matter indicating activity-based emissions and filtration effectiveness.
• CO2 for occupancy inference and ventilation tuning.
• TVOCs for off-gassing from materials and processes.
• Temperature and humidity to support comfort and sensitive operations.
• Differential pressure to help maintain directional airflow between areas.

Work-ready features:

• Durable housings and protective accessories suited for industrial use.
• Clear displays readable in varied lighting, with simple menus that reduce training time.
• Data logging and export to support reports, CAPA documentation, and continuous improvement.

TSI has supported manufacturing for decades with precision instrumentation. Our handheld IAQ meters reflect that experience — combining measurement fidelity and usability so your team can move quickly from question to conclusion. Pair handhelds with continuous monitors to build a comprehensive IAQ program that serves operations, quality, and EHS objectives.
