Flow Rate
Supply Power

The new WTM-1000 mini wind tunnel from OMEGA™ gives a highly uniform flow rate at 4 selectable fixed air speeds, yet it costs less than competitive brands. The fixed air speeds range from 2.5 m/s (492 fpm) to 15 m/s (2953 fpm). With the remote option, the user can control and vary the wind tunnel air speed externally by connecting a potentiometer. The internal 10 cm (4") diameter test chamber is large enough to accommodate either hot-wire or vane-type anemometers. The unit is powered by 90 to 250 Vac. Each WTM-1000 comes with an NIST calibration certificate for the 4 fixed air speeds.

If we want to have heated airflow around 55 to 70 degree C, could we use pipe to connect this wind tunnel to our oven?

Asked by: Anonymous
Thank you for your inquiry on the wind tunnel. These wind tunnels were designed for laboratory environments at typical room temperatures. Although the test chamber is thick and would probably hold up to that temperature, unfortunately, the fan blades would not maintain their shape as they are plastic and much thinner.

We have this unit but are finding it very difficult to use for calibration for the variety of anemometers that are sent to us. Are you able to assist us with getting accurate numbers on different brand/models of anemometers?

Email us all your questions/concerns regarding functionally of this wind tunnel to We will review it and get back to you.

Does this unit use a Pitot-static tube to indicate the wind tunnel air speed?

Asked by: vic54
Thank you for your inquiry about the wind tunnel. A Pitot tube is not used to correct for pressure when it is tested for calibration. The manual indicates the correction equation applied to correct for standard conditions.
