Electronic monitors feature lights that indicate normal or alarm status; audible alarm warns of potentially dangerous airflow conditions. Set the alarm at any point between 70 to 250 ft/min. Analog output is 0 to 4 V. What's included: mounting hardware, tubing, sidewall adapter, and a 115 VAC power adapter with a 6-ft cord. Use these advanced airflow monitors to assure the safety for all lab personnel. Monitors maintain accurate response even when using low-flow hood conditions. Alarms activate based on sustained low-flow condition. Use pushbuttons to set alarm and perform easy two-point calibration. Monitors will also indicate high sash condition (requires proximity switch, not included) with configurable time delay. Record hood performance using RS-232 connection to computer. Graphic display model 33556-60 shows current flow velocity and provides bar graph depiction of recent hood airflow performance. Calibration instructions appear on-screen. Use night setback to constrain audible alarm usage or use up to 3 relays to switch other laboratory devices based on hood alarm activation. What��s Included: Mounting bracket for surface mount. Call our Applications Specialists if flush mount (requires 2�� x 3�� opening) is preferred.
