6200D LoFlo Balometer by TSI Alnor - Capture Hoods for Low Air Volumes

The 6200D LoFlo Balometer by TSI Alnor is a low-flow capture hood designed for precise airflow measurement at small diffusers, slot diffusers, and low-volume registers where standard balometers are too large or inaccurate. It measures airflow from 10–500 CFM with an accuracy of ±3% ±5 CFM and weighs just 6.5 lbs for easy one-person operation. With a battery life of over 10 hours, it is well-suited for HVAC balancing, cleanroom qualification, laboratory fume hood testing, and energy audit work where small-opening measurement accuracy is critical.

Frequently Asked Questions

It measures supply and return air volume at diffusers and grilles in low-flow HVAC applications — labs, cleanrooms, isolation rooms, and variable air volume systems where a standard capture hood's resistance would distort the reading. Measurement range is 10–500 CFM.

Use the LoFlo when expected flows are below 500 CFM or when added hood resistance could affect accuracy, particularly in critical environments. Use the EBT731 (25–2,500 CFM) for standard commercial HVAC commissioning where flows are well above the low-flow range.

At low flow rates, a standard hood's internal resistance can measurably change the airflow it's trying to measure. The LoFlo is designed to minimize this effect so you measure the system's actual performance rather than the hood's influence.

No — it's real-time display only. If your deliverable requires logged datasets, plan to record readings manually or select a logging-capable instrument.

Center the hood, ensure no gaps at the diffuser face, and keep orientation consistent across readings. Allow readings to stabilize before recording. HVAC cycling can cause variation — document fan speed and system state with each measurement.

Balometer base, 2×2 ft hood with frame and poles, user manual, carrying case, and calibration certificate.

$125/day and $300/week. Pricing beyond two weeks is by quote. For lab or cleanroom TAB projects with many low-flow diffusers, the weekly rate is typically more economical — most multi-room certification projects take more than two days.
