Alnor LoFlo Balometer Capture Hoods

Low-volume terminals pose a measurement challenge: flows are gentle, often highly uniform, and easily disturbed. Alnor LoFlo Balometer Capture Hoods address this challenge with a compact, sensitive design that helps technicians quantify low flows at laminar diffusers, clean benches, and specialty terminals across life science facilities.

Made for Low-Flow Accuracy

• Hood geometry promotes stable readings at laminar flow devices commonly used in ISO-classified spaces.
• Sensitive measurement capability captures low volumetric flows without requiring large pressure differentials.
• A compact form factor helps maintain access in tight spaces and minimizes interference in critical zones.

Where LoFlo Fits Best

• Cleanroom laminar diffusers: Verify uniform discharge and document total room supply for pressure cascade strategies.
• Clean benches and localized clean zones: Measure gentle supply to support device performance checks.
• Pharmacy compounding suites: Document terminal flows during initial qualification and routine monitoring under USP <797>/<800>-aligned SOPs.
• Isolation rooms and specialized spaces: Quantify low flows where over-ventilation is not desired and directional control matters.

Productivity in the Field

• Interchangeable hood sizes help match device geometry, improving repeatability and reducing setup time.
• Clear displays and straightforward controls keep measurements consistent across technicians and shifts.
• Data logging and export options simplify reporting, trending, and quality documentation.

Best Practices for Low-Flow Measurements

• Choose a hood that fully captures the discharge area to reduce bypass.
• Allow measurements to stabilize, and confirm repeatability with second passes.
• Document diffuser type, hood size, and environmental conditions for traceable records.
• Combine terminal measurements with differential pressure and particle counts for a comprehensive environmental profile.

Service and Calibration

• Periodic calibration supports ongoing confidence in low-flow readings. Traceable certificates help align with quality system requirements and audit-ready documentation.

With the Alnor LoFlo Balometer Capture Hood, life science teams can measure low flows accurately and efficiently — supporting cleanroom validation, certification routines, and routine monitoring with data that is ready for analysis and action.
