40 or higher. Together, they measures air velocity 0…30 m/s. The equipment can display air flow and is suited to measure in ventilation ducts according to EN 16211:2015 or EN 12599:2012 and in fume hoods according to EN 14175:3-4:2019.
SWA 32 is a more accurate version of SWA 31. SWA 32 has smaller corrections on the calibration certificate.

| Description | |
| On the 66 cm long telescopic shaft there is a scale for easy placement in ventilation ducts. The measurement is displayed directly or with a number of points as average, max and min. | |
| Flow calculation | |
| The duct dimension as | diameter, height and width or area, can easily be inserted into Swema 3000 to make the instrument calculate and display the flow in l/s , m3/h or CFM. The most common standard dimensions are selected directly. |
| To get a good flow value in the duct the instrument makes an average of point measurements over the selected area. According to research, due to friction at the wall, there is a reduction factor k2, that reduces the calculated value. | |
| Autosampling | |
| For grilles, you enter the height x width using auto-sampling and a smooth sweeping technique across the grilles, Swema 3000 calculates the rate of air flow in l/s, m3/h or CFM. Set the time constant down to 0.025 sec to get 4 measurements /sec. Average, standard deviation, max and min is automatically calculated. | |
| Fume hood (cupboard) measurements | |
| SWA 31 measurements complies with EN 141753-4. |
