Anemômetro térmico
A precision hot-wire thermal anemometer for low air-velocity measurement, temperature indication and cleanroom airflow surveys at grilles, hoods and open work zones.
- Sensitive hot-wire measurement for low-speed cleanroom air.
- Slim telescopic probe with minimal flow disturbance.
- Averaging and logging for structured airflow traverses.
Introdução do produto
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.
Características-chave
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.
Preocupações do produto do cliente
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.
