Air velocity meter with 45 mm vane

The TENMARS TM-414 measures air speed, temperature, humidity and absolute pressure using a 45 mm four-vane sensor. It captures readings from 0.4 m/s and operates between -20 °C and 50 °C. Data hold, max/min/average calculation and a 99-record memory with recall are built in. A backlit display and selectable auto power-off complete the feature set.

Technicians verifying HVAC outlets

The instrument suits professionals who need simultaneous air-flow, temperature, humidity and pressure spot checks at supply grilles. It is not intended for users who require data logging beyond 99 records or wireless transfer of measurements. Buyers needing a probe diameter other than the supplied vane should consider alternative models.

45 mm vane diameter dictates grille access

The 45 mm vane determines which supply outlets the meter can be inserted into for direct measurement. If the target grilles are smaller than this diameter, the unit cannot take readings at the face of the outlet. Confirm the opening size before purchase.

Questions about this item

Will the 45 mm vane or internal sensors need periodic recalibration or replacement?

The vane is a 45 mm plastic impeller and the unit includes humidity and absolute pressure sensors; no user-replaceable sensor modules are described.

What measurement limit is reached first during continuous logging?

The onboard memory stores 99 records, so the log buffer fills before any other specified limit.

How much heat or noise does the meter produce when left running all day?

The instrument is a handheld meter with auto power-off and backlight; it generates no audible fan noise and negligible heat during extended use.
