TSI Alnor 6200D LoFlo Balometer. In Stock and Ready to Ship.
Alnor 6200D LoFlo Balometer with Capture Hood measures supply or return air flows from 10 to 500 cfm (17 to 850 m3/h) with +/- accuracy of 3%. This LoFlo balometer is the ideal way to measure very low volumetric airflow and perform measurements in tight spaces.
Key Features:
- Small size and weight ideal for hard to reach places
- For small diffusers only a base can be used
- Measures low air flow 10 to 500 cfm (17–850 m3/h) (4.7–236 l/s)
- Accurate ± (3% + 5 cfm)
- 10 hours of continuous work provided by 4 batteries
- Comes with NIST calibration certificate
- Certified by CEC (California Energy Commission)
The TSI 6200D light weight – only 6.5 lbs - makes it ideal for residential or commercial use. The small and compact size – only 34.5 inch high - allows for use in hard to reach places, where regular size air capture hoods cannot be used.
The hood fabric and frame is 2’x2’; however, when you have smaller grilles, diffusers, or registers, you can use the instrument base only, without a hood, to perform all measurements of the HVAC ventilation system.
This Alnor LoFlo balometer uses a vent system devised by the company. The system reduced restriction to air flow introduced by the instrument itself; therefore, allowing to measure a relatively wide range of air flow.
