Using Your Phone is Smarter
The other key advantage with the Sauermann DBM 620 series flow hoods is that they use a readily available smart phone (or tablet) for their measurement display. Many competitive brands of flow hoods on the market use their own expensive and proprietary meters / display units and when these fail (and they regularly do) they need to go back to the supplier or overseas manufacturer for VERY costly repairs or replacement. In contrast, smart phones are very inexpensive, very reliable and are widely available.

The Sauermann DBM 620C is engineered to measure a wide range of airflow, from low to high velocities, and accommodates a variety of grille sizes and shapes. This flexibility makes it ideal for a variety of ventilation applications. Built with high-quality materials, the DBM620 is tough and reliable, designed to withstand the rigors of everyday use in the field. Whether you’re working in a commercial building or an industrial setting, this unit is built to last.
