Portable Thermoanemometer TSI Airflow TA440

Descripción general del producto. The TSI Airflow TA440 is a professional-grade portable thermoanemometer designed for precise HVAC testing, commissioning and indoor air quality assessments. It combines a sensitive hot-wire sensor with multi-parameter measurement to deliver reliable air velocity, temperature and humidity readings with rapid response and excellent repeatability. Compact, robust and easy to operate, the TA440 streamlines airflow diagnostics on site with intuitive navigation, an easy-to-read backlit display and smart functions that help you obtain stable, trustworthy results faster.

Key Benefits and Applications

• All‑in‑one measurements — Capture air velocity, temperature and relative humidity with one instrument, reducing the need for multiple tools and accelerating HVAC balancing, ventilation checks and IAQ surveys.
• Confidence at low and mid velocities — The hot‑wire probe offers high sensitivity for diffusers, grilles and ducts where air speeds are modest, helping you detect small performance deviations before they become costly issues.
• Fast volumetric flow assessments — Enter duct dimensions and shape to obtain volumetric flow in m³/s or m³/h directly on the instrument, enabling quick supply and extract comparisons during commissioning.
• Consistent, repeatable results — On‑screen stabilisation aids, hold, min‑max and averaging functions support repeatable test routines and reduce operator variability when documenting performance.
• Built for field work — A rugged handheld design with a telescopic probe, clear display and ergonomic keypad helps you work efficiently in plant rooms, service corridors and above-ceiling spaces.
• Versatile applications — Ideal for HVAC testing and balancing, laboratory and cleanroom airflow checks, filter face velocity surveys, fume cupboard face velocity spot checks and energy‑efficiency optimisation.

Featured technical specifications

• Measured parameters — Air velocity in m/s, air temperature in °C, relative humidity in %RH, with calculated wet‑bulb and dew point, plus volumetric flow in m³/s or m³/h when duct size is entered.
• Hot‑wire telescopic probe — Slim, directional probe engineered for accurate point measurements across diffusers and inside ducts, supporting traverse methods and multi‑point averaging.
• Display and interface — High‑contrast backlit screen with intuitive menus, numerical and icon indicators, data hold and real‑time statistics to speed up decision‑making at site.
• Averaging and statistics — Time‑averaged and multi‑point averaging modes, with min, max and average values shown to document system behaviour during test runs.
• Volumetric flow calculation — User input for round or rectangular duct dimensions enables direct flow readings, reducing manual calculations and transcription errors.
• Units and regional settings — Fully SI‑based readouts and configuration, including m/s for velocity, °C for temperature, %RH for humidity and m³/s or m³/h for flow.
• Power and portability — Battery‑powered handheld instrument designed for full‑day field use, with a compact form factor that fits service bags and elevates on‑site productivity.
• Durability and service — Robust construction suited to demanding mechanical services environments, with professional calibration support to maintain measurement confidence over time.
