 Features The AirGard 385 continuously monitors fume hood face velocity by measuring the air velocity of clean air from the room passing through the air inlet on the front of the monitor. The unit then reports this information visually through a digital display and colored lights, as well as with a continuous audible alarm when the face velocity is in an alarm condition. This information can be sent to a remote location by means of a dry contact relay output and 0-4 volt analog output. The monitor mounts flush to the fume hood surface and fits into a single electrical receptacle box knock-out. Specifications Digital Display 3digit, 7-segment liquid crystal display.
