Handheld Air Velocity Meter for HVAC Checks

The TM-413 measures air speed from 0.4 to 45 m/s and calculates flow in CMM or CFM up to 9999. It also records temperature from -20 to 60 °C and relative humidity with a resolution of 0.1 %. A 45 mm four-vane sensor provides the stated 3 % plus 0.2 m/s accuracy.

Practical Limits of Vane Anemometry

The 45 mm vane requires direct exposure to the air stream and cannot measure inside ducts smaller than the sensor face. Readings above 45 m/s fall outside the calibrated range and the stated accuracy no longer applies. The 99-record memory stores spot measurements but does not log continuously over time.

Compatibility Checks Before Ordering

Verify that the measurement locations allow physical access for a 45 mm vane probe. Confirm that the expected air velocities stay within the 0.4 to 45 m/s range and that the operating temperature remains between -20 and 60 °C. The meter includes absolute pressure sensing, so no separate barometer is needed for the specified functions.

Questions about this item

Which TM-413 model should I choose if I need air velocity, temperature, humidity, and air flow calculation?

The TM-413 measures air velocity from 0.4 to 45 m/s, temperature from -20 to 60 °C, humidity, and calculates air flow in CMM or CFM up to 9999.

What does the 0.4 to 45 m/s range mean when I use the meter on site?

It detects air speeds as low as 0.4 m/s and as high as 45 m/s with a resolution of 0.1 m/s and an accuracy of 3 % plus 0.2 m/s.

What measurement standard does the anemometer follow and what does that limit in practice?

The instrument uses a 45 mm four-vane sensor and an absolute pressure sensor, storing up to 99 records with backlit display and auto power-off.
