Digital Hot-film Anemometer for Air-flow

The TeKit AR866A is a digital hot-film anemometer designed for technicians who measure air velocity and temperature in ducts, laboratories or HVAC systems. It suits engineers, facility managers and environmental testers who need a portable instrument with data-logging capability. Buyers requiring a pitot-tube or vane-style probe should look elsewhere.

Hot-wire Sensor Measures Up to 30 m/s Velocity

The single specification that decides suitability is the hot-wire sensor range of 0 to 30 m/s for air velocity with an accuracy of ±1% ±0.1. This probe type excels in low-speed, small-space measurements where a slender sensor is required. If your application demands readings beyond 30 m/s or a different sensing principle, this model will not meet the need.

Low Power Draw from 9 V Battery with Auto-off

Normal operation draws minimal current from a single 9 V battery (not included) and the unit powers off automatically after five minutes of inactivity. The LCD backlight activates only when needed, keeping thermal output and audible noise negligible during handheld use. No external power supply or active cooling is involved.

Questions about this item

What does the 40 m/s maximum speed mean when I am using the meter in a duct?

The instrument can measure air velocities up to 40 m/s, so it covers high-velocity ducts and fan outlets without saturating.

How does the USB connection limit the data I can transfer to a PC?

The USB link lets you download the 500 stored records and stream live readings to the supplied software for logging and analysis.

What physical space does the probe need to fit into a grille or pipe?

The slender hot-wire probe is designed for small-space measurement and the handle can elongate to reach deeper into grilles or pipes.
