Model 660 Air Velocity Monitors are a practical, affordable way to continuously monitor for safe airflows through laboratory fume hoods. They are typically installed in the fume hood side fascia and connected to the interior sidewall via 1-1/8" 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.
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.
Model 660, Air Velocity Monitor. Includes 3’ flexible tubing, pre-fittings and 90° elbow, 120 VAC to 24 VAC power transformer.
