Product Overview/Usage:

Hampshire Controls' "Air Flow Monitor" is a single probe instrument used for continuous monitoring of mass air flow levels within laboratory biosafety cabinet/laminar flow hoods. The unit also includes audible and visual alarm status indication of high and low flow levels and an (SPDT) output for alarm status indication.

For monitoring air flow, a single, 5/16" diameter probe is used. Once it is inserted into the flow stream properly (see video below), it will respond rapidly, accurately and repeatably. After probe positioning, you only need to set the flow value to "just above" the acceptable desired audible/visual alert status indication threshold. Then your all set.

Should air flow rates change based on your established alert condition set point level, a yellow indicator light will illuminate. In addition, if flow rate drops below established set-point value for approximately 10 seconds, a red status indicator light will begin to flash and an audible alarm will sound.

Nominal flow range for standard configurations is either between 50 and 500 feet/minute (low-range version), or between 500-2500 feet/minute (for high-range versions). Standard units are designed for operation in air temperatures between 18°C and 28°C. However, other temperature and flow ranges are available upon request.
