Fume Hood Monitors – Convenient Airflow Safety Solutions

Do you need a convenient, capable fume hood monitor?

The Rooster™ Alarm and Rooster™ Monitor100 fume hood monitors provide full-time tracking of air velocities within cabinet or exhaust systems to ensure that airflow does not fall below user-defined thresholds. If air velocity drops below a preset level, the Rooster activates an airflow alarm signal to indicate that a potentially unsafe condition exists. Fume hood monitors also alarm audibly and visually to alert local staff.

The Rooster Alarm is designed as an easy retrofit option for fume hoods and biosafety cabinets. It is a fast, reliable way to achieve airflow safety and help you meet NSF/ANSI-49 and OSHA guidelines. The Monitor100 is a next-generation airflow monitor with a color touchscreen display for users who want to see measured values and airflow status in real-time. Monitor100’s many advanced features include password-protected access tiers, alarm delay, latching, ringback, and event logging for more demanding critical containment applications. Both Rooster Alarm and Monitor100 offer a choice of side-flow sensor for negatively pressurized cabinets or insertion probe for exhaust ducts.

Fast, Intuitive Setup

Degree Controls fume hood monitors are easy to install and operate. The Rooster Alarm features a single push-button for airflow calibration while the Rooster Monitor100 uses a quick, two-step calibration process.


The display module is typically
mounted to the front of the fume hood.

Fume hood monitors can be mounted on a wall surface or recessed in a standard electrical gang box.

Custom Branding

For OEMs, certification companies and laboratories with a large number of hoods, we offer customizations for our airflow monitors that allow you to showcase your business. Fume hood monitors can be built with a graphic overlay displaying your company’s name and logo.

Rooster Monitor100 Critical Containment Airflow Monitor

Fume Hood

A fume hood is a primary engineering control to contain chemicals and exhaust hazardous gases and vapors away from the user and the laboratory environment. Fume hoods and fume cupboards operate by continuously pulling room air in and delivering airflow away from the user. Air is then safely exhausted or recirculated. As a ventilated system, if fume hood airflow changes, the risk of occupants being exposed to hazardous chemicals increases.

Face Velocity

Face velocity is the measured air speed at a fume hood’s face opening. It is a key measurement of how well a fume hood is performing. If face velocity is too low, the fume hood system may not be operating as it should be.

Fume Hood Monitoring

Chemical fume hoods need fume hood monitors to measure airflow. Rooster fume hood monitors measure the air velocity of fume hoods to ensure that containment and ventilation are adequate, providing visual, audible, and remote alarms if air velocity drops below a preset level.
