Digital Manometer for Exhausting Containment Cabinets

The Digital Manometer Monitor uses an integrated digital pressure transducer to monitor exhaust system negative pressure. The monitor indicates through both a segment display and LEDs. The segment display is green and operates to + 0.01" w.g. sensitivity. The LEDs indicate acceptable pressure (green), caution or near alarm points to within 0.005" w.g. (yellow) or alarm condition (red).

Digital Manometer Sentry Installation

The Digital Manometer Sentry System is an all electronic version of NuAire's successful Labgard Sentry System. This all new system is designed to provide an additional measure of safety in the Biological Safety Cabinet by informing the operator when cabinet airflow drops below the critical level per NSF Standard #49, (that level at which air velocities within the cabinet may be low enough to permit contaminants to escape and enter the cabinet and room, respectively, due to normal disruptions of the air barrier).

NU-946B Airflow Monitor

The NuAire Airflow Monitor can be used for practically any application requiring the mass flow of an air stream to be monitored for minimum acceptable flow. A stable/repeatable response to airflow detection is achieved by using two thermistors: One that is self-heated and one that is measuring ambient. As air is passed over the thermistors the heated thermister is cooled, generating a difference in resistivity that translates into the flow rate. The second thermister provides the temperature compensated ambient reference.

NU-959 Portable UV Light Installation Instructions

The NuAire portable germicidal ultraviolet lamp is primarily intended for the destruction of bacteria and other microorganisms in the air or on directly exposed surfaces. Approximately 95% of the ultraviolet radiations from germicidal tubes are in the 253.7 manometer region. This is a region in the ultraviolet spectrum which is near the peak of germicidal effectiveness. The exposure necessary to kill bacteria is the product of time and intensity.
