Air velocity and environmental meter

The TM-412 measures air speed, temperature, humidity and absolute pressure with a 45 mm four-vane probe. It offers a sensitivity of 0.4 m/s and suits electricians or HVAC technicians who need spot readings at outlets and ducts. Data hold, max/min/average and a backlight simplify field work.

Suited for single-point airflow checks

Technicians verifying ventilation performance or balancing air distribution will find the 99-record memory and recall function useful. Buyers who need continuous logging, remote monitoring or a larger vane for high-volume ducts should look at other instruments.

0.4 m/s sensitivity threshold

This figure determines the slowest air movement the meter can reliably detect. If the application involves very low-velocity flows below that value, the TM-412 will not capture them.

Questions about this item

How much power does the TM-412 draw during all-day use?

The TM-412 includes an auto power-off feature with a disable function to manage battery life during extended sessions.

What must I already own for the TM-412 to work out of the box?

The meter ships as a single unit in a box; no additional probes or accessories are required for basic operation.

Can the TM-412 log data alongside my older 30 mm vane anemometer?

The TM-412 stores up to 99 records with recall, while its 45 mm vane and 0.4 m/s sensitivity complement spot checks from smaller-vane tools.
