Flow Hood Calibration Laboratory

Flow hood calibration

Quick-Quote-Button

CIH Equipment calibrates and verifies the performance of flow hoods (balometers) using best practice metrology methods. With the latest test equipment, instruments and a dedicated test room, every reading obtained is corrected for the environmental condition on the day. We compare your flow hood against our reference standard under the most accurate and realistic conditions, with both a supply and return register. We achieve this by means of taking the required velocity measurements both horizontally and vertically, average the readings, and compare to our NIST traceable reference. Our procedures are designed to maximize the accuracy, repeatability, and reproducibility of your velocity measuring instruments.

Flow Hood Balometer

An airflow capture hood or balometer is a device used for measuring the volume of air coming out of grilles and diffusers in HVAC systems. “Balometer” is actually a term coined by Alnor in 1983 that has become synonymous with “airflow capture hood” today.

Flow Hood Calibration

It is recommended that your LoFlo Balometer® Capture Hood be sent once a year for a calibration check. When shipping the LoFlo Balometer® Capture Hood for calibration, pack it carefully, and follow the Instructions for Return in your manual.
