Alnor AirGard^® 350 CEM Bio-Safety Cabinet Monitors

The AirGard 350CEM continuously monitors bio-safety cabinet exhaust velocity by measuring the air velocity of clean air passing through the remote probe mounted in the transition section above the HEPA filter or in the ductwork. The monitor then reports this information through readily understandable means to the user. An electronic bargraph moves back and forth through universally recognized red (danger), yellow (caution) and green (safe) colored zones as the velocity changes. Corresponding large colored lights also illuminate. A continuous audible alarm alerts of a dangerous situation when the face velocity is in an alarm condition. This information can be sent to other personnel in a remote location by means of a dry contact relay output. A digital display can be enabled to view velocity quantitatively. The monitor mounts with a bracket (provided) on the ledge of a bio-cabinet and operates from a low voltage transformer (provided).
