Vane anemometer for airflow checks

The REED R4000SD is a rotating-vane anemometer that measures air velocity from 79 to 5906 fpm and air temperature from 32 to 122 °F. It reads in ft/min, km/hr, knots, m/s and mph with 1 fpm resolution and ±1.5 °F temperature accuracy. A 2.8 in diameter probe and carrying case are included.

Suited for HVAC and industrial spot checks

Technicians who need quick duct traverses, filter-face velocities or grille balancing will find the range and multi-unit display useful. Buyers who require hot-wire sensitivity for very low flows, data-logging capability or dew-point measurement should consider other instruments.

Rotating-vane probe with 79–5906 fpm range

The 2.8 in vane sets the lower measurable limit at 79 fpm, so air movement below that speed will not register. Confirm that the expected velocities in your application stay above this threshold before purchasing.

Questions about this item

How much power does the R4000SD draw when it runs all day on site?

The R4000SD is a battery-operated handheld meter; it draws only the tiny current needed for its LCD and vane sensor, so a standard 9 V cell powers it through a full working day.

What must I already own so the R4000SD can log air-velocity readings to a spreadsheet?

The R4000SD has no data-logging or PC interface, so you need nothing extra to take spot readings; for continuous logging you would need a different instrument.

Can the 2.8 in rotating vane on the R4000SD sit alongside my older hot-wire probe without interference?

The 2.8 in vane probe measures bulk airflow mechanically and does not emit heat or signals that would disturb a hot-wire sensor used nearby.
