商品紹介

This thermal anemometer uses a heated miniature sensor whose cooling response tracks local air velocity with high sensitivity at low speeds. A slim telescopic probe enters grilles, ducts and confined test locations with limited flow disturbance, while the handheld meter provides velocity, temperature, averaging and data-storage functions for systematic qualification work.

主要な特徴

Hot-wire sensing resolves low velocities that are difficult for conventional vane instruments.

Slim telescopic probe reaches ducts and overhead outlets with minimal flow obstruction.

Simultaneous velocity and air-temperature readings support ventilation diagnostics.

Timed and multi-point averaging stabilizes measurements in fluctuating air streams.

Selectable duct area enables calculated volumetric-flow results.

Stored readings can support traverse records and qualification documentation.

お客様の製品に関する懸念事項

Low-speed unidirectional airflow requires a sensitive sensor that can enter restricted test points without materially changing the velocity being measured.

Very low cleanroom air speeds can fall below the useful sensitivity of a compact vane.A heated miniature sensor responds to small changes in convective cooling for dependable low-velocity readings.

A bulky probe can disturb the flow inside a grille or narrow duct.The slender telescopic shaft and small sensor tip reduce blockage at the measurement point.

Local turbulence makes a single instantaneous value unrepresentative.Timed and multi-point averaging produces a more stable result across the prescribed traverse.

Long qualification surveys are vulnerable to transcription errors.Onboard storage keeps point readings and statistics available for later review and reporting.
