flow-through sensor incorrect implementation

While probe sensors are the most widely used in the industry when it comes to certifying air velocity in fume hoods and biosafety cabinets, longer-term particulate and chemical exposure degrades accuracy and reliability over time, and within cabinets with a movable sash and a local fan, correlating duct-to-face velocity can be particularly difficult.

In order to overcome these limitations, DegreeC recommends using the Sidewall Sensor. Designed specifically for critical containment applications, the sidewall sensor acts as a flow-through assembly, drawing in ambient air rather than contaminated exhaust air in order to measure airflow conditions with not only greater accuracy, but longer-term reliability. Used with the Rooster™ Alarm, full time tracking of air velocities ensures air movement never falls below user-defined thresholds. Additionally, with connection via a flexible tube, the sidewall sensor can be passed through dual-wall cabinets or in areas where space is a factor.

When choosing to utilize a sidewall sensor, the fume hood or biosafety cabinet that the sidewall sensor will be installed in should be positioned away from doors or areas with significant people traffic. These factors can add unwanted turbulence, decrease the overall accuracy of the sensor, and compromise the testing space.
