Portable Logger Thermoanemometer TSI Airflow TA430

The TSI Airflow TA430 is a compact, professional-grade thermoanemometer designed for fast, reliable ventilation testing. With its long, telescopic probe and intuitive interface, it delivers high-accuracy air velocity and temperature measurements, onboard data logging for more than 12,700 samples, and built-in volumetric flow calculation to streamline HVAC balancing, duct traverses and critical environment checks. Robust, lightweight and ready to work out of the case, the TA430 helps you complete commissioning and troubleshooting faster—available from Stratosens.com.

Key Benefits and Applications

• Accurate results you can trust — High-precision thermal anemometry ensures dependable readings for ventilation audits, TAB work and compliance reporting.
• Faster commissioning and troubleshooting — Measure velocity and temperature simultaneously, view up to three parameters on screen, and make confident adjustments in fewer visits.
• True portable logging — Store large datasets on board for trending and proof of performance, then review results in the field to validate measurements before leaving site.
• Volumetric flow at a glance — Enter duct size in seconds and let the instrument compute actual or standard flow, reducing manual calculations and errors.
• Reach every test point — The 1.016 m telescopic probe accesses deep ducts, ceilings and hard-to-reach grilles, ensuring representative measurements across the section.
• Ready for critical environments — Ideal for cleanrooms, labs and healthcare spaces where airflow consistency and documentation are essential.
• Rugged and ergonomic — Lightweight body, large readable display and included hard case make daily carry and site work comfortable and safe.

Featured technical specifications
