Flow Hood Calibration Laboratories

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.
