Contact SupplierModel 660 Air Velocity Monitor
continuously measures fume hood airflow
model 660 air velocity monitors are a practical, affordable way to continuously monitor for safe air flows through laboratory fume hoods. They are typically installed in the fume hood side fascia and connected to the interior sidewall via 1-18" flexible tubing. As the exhaust fan draws air through the device, a sensitive constant temperature thermistor measures flow and lights a green (normal), yellow (high) or red (low) led. An audible alarm also warns of low flow and requires manual resetting. Mounting holes fit standard single gang electrical box.
product applications : warns user if insufficient fume hood face velocity is encountered.
