The fume hood controller model number is part code HMS1655. This model includes a controller module that mounts on the top of the monitored fume hood, and a mouted velocity sensor on the interior sidewall of the fume hood. The sidewall velocity sensor measures face velocities at the sash opening up to 200 ft/min with an accuracy of ±2 ft/min.
