Portable Multi‑function Ventilation Equipment TSI Airflow TA465P

The TSI Airflow TA465P is a portable multi‑function ventilation instrument designed for professionals who need reliable on‑site measurements with maximum flexibility. It combines an integrated micromanometer for precise differential pressure with barometric pressure sensing and inputs for two K‑type thermocouples, while accepting “smart” plug‑in probes for air velocity, temperature, humidity, CO₂, CO and VOCs. With a large graphical display, data logging, Bluetooth connectivity and intuitive menus, the TA465P streamlines HVAC commissioning, testing and balancing, cleanroom certification and indoor air quality assessments. Choose the TA465P at Stratosens.com to elevate productivity, accuracy and traceability in every project.

Key Benefits and Applications

• All‑in‑one flexibility — Start with built‑in differential and barometric pressure, then expand with plug‑in probes for velocity, RH, CO₂, CO and VOC measurements to cover HVAC, TAB, cleanrooms and IAQ studies with one platform.
• Faster field work — View up to five parameters at once on a bright graphic display, apply on‑screen duct sizes and test IDs, and log data continuously to reduce rework and speed reporting.
• Traceable accuracy — “Smart” probes store their own calibration data and can be serviced independently, helping you maintain audit‑ready documentation and minimize downtime.
• Seamless data handling — Transfer datasets wirelessly via Bluetooth or by USB, simplify documentation, and integrate results into your commissioning or certification reports without manual transcription.
• Rugged and portable — Handheld design, long battery life and a protective carry case make it easy to use on rooftops, plant rooms, laboratories and clean areas.
• Wide application coverage — Perform duct traverses with pitot tubes, verify room pressurization and containment, check fume hood performance, balance supply and extract flows, and evaluate thermal comfort and IAQ.

Featured technical specifications

• Differential pressure measurement — Measurement range from −3,735 Pa to +3,735 Pa with typical resolution of 0.1 Pa and accuracy of ±1% of reading ±1 Pa. Overpressure protection up to approximately 48 kPa for sensor safety.
• Barometric pressure — Measurement range approximately 68.9 kPa to 124.1 kPa with accuracy of ±2% of reading to support density corrections and standard versus actual flow calculations.
• Air velocity with pitot tube (accessory) — Measurement capability from 1.27 m/s to 78.7 m/s with typical accuracy of ±1.5% at 10.16 m/s and resolution of 0.01 m/s for high‑speed ducts and large systems.
• Air velocity with thermal anemometer probe (optional) — Measurement capability from 0.15 m/s to 50 m/s with accuracy of ±3% of reading or ±0.015 m/s, whichever is greater, ideal for low‑flow diffusers and room flows.
• Temperature with optional probe — Operating measurement range from −10 °C to 60 °C with typical accuracy of ±0.3 °C for precise psychrometric calculations.
• Relative humidity with optional probe — Measurement range from 5% to 95% RH with typical accuracy of ±3% RH to support dew point and wet‑bulb calculations.
• Data logging capacity — Stores over 26,500 samples with up to 100 test IDs. Logging interval user selectable from 1 s to 1 h to match the test method.
• Responsive measurements — Typical response times of 0.1 ms for pressure, 200 ms for velocity, less than 1 min for humidity to 66% of final value, and about 2 min for temperature to 66% of final value ensure efficient traverses and spot checks.
• Connectivity and display — Bluetooth communication and USB interface, large multi‑line graphic display capable of showing up to five parameters simultaneously for clear, on‑site decision making.
• Thermocouple inputs — Two K‑type thermocouple channels for additional temperature measurements and heat flow calculations when required.
• Power and battery — Powered by four AA batteries or an external AC adapter at 9 V DC. Designed for long sessions in the field.
• Dimensions and weight — Compact handheld housing approximately 9.7 cm × 21.1 cm × 5.3 cm with a weight around 0.36 kg to reduce fatigue during long surveys.
• Included items — Instrument with differential pressure sensor, carry case, four alkaline batteries, USB cable, operation and service manual, and calibration certificate to get you working immediately.
