model 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. specifications service:air and non-combustible, non-corrosive gases. high setpoint range:0-275 fpm (0-1.397 m/s). low setpoint range:0-150 fpm (0-.792 m/s). repeatability:±7% of full span, 0-50 and 150-275 fpm; ±5% of full span, 50-150 fpm. compensated temperature range:50 to 90°f (10 to 32.2°c). operating temperature range:32 to 120°f (0 to 48.9°c). power supply:24 vac, 3 watts maximum. response time:6-10 seconds. warm-up time:3-5 minutes (no flow). audible alarm:75 db between 3-10 feet. weight:3 oz (85 g). mounting hardware:(2) #6 x 1" sheet metal screws, (2) 6-32 x 7/8" machine screws. related products model vt120 integral vane thermo-anemometer model vt120 integral vane thermo-anemometer model 480 vaneometer™ swing vane anemometer model 480 vaneometer™ swing vane anemometer model vt-200 vane thermo-anemometer model vt-200 vane thermo-anemometer
