Balometer & Volume Flow Hood Calibration

What are Balometers (Volume Flow Hoods)?

Balometers, also known as volume flow hoods or flow capture hoods, are essential tools used by HVAC (Heating, Ventilation, and Air Conditioning) engineers and installers to measure the airflow rates in ducts and vents. These instruments ensure that HVAC systems are operating efficiently and effectively, providing optimal airflow and comfort in residential, commercial, and industrial settings. Leading manufacturers include Testo, TSI, Alnor, Kanomax, and Shortridge.

Importance of Calibration

Regular calibration is critical to maintaining the accuracy and reliability of balometers. Calibration ensures precise measurements, enabling accurate diagnosis and resolution of airflow issues. Without proper calibration, inaccurate readings can lead to inefficiencies in HVAC system performance, increased energy costs, and compromised indoor air quality.

Our Calibration Process

At PASS, we offer calibration services for all types of balometers and volume flow hoods. Our state-of-the-art wind tunnel, capable of generating airflow speeds from 0.1 m/s to 60 m/s (50 – 4300m3/h which is around 29.5 to 2531 cfm), provides the perfect environment for precise calibration. This extensive range allows us to simulate a wide variety of real-world conditions, ensuring your equipment is accurately calibrated for any scenario.

Our calibration process includes:

1. Initial Inspection: Thorough inspection to identify visible defects or issues affecting calibration accuracy.
2. Calibration Setup: Your device is placed on our UKAS calibrated wind tunnel for controlled airflow conditions.
3. Precision Measurement: Using high-accuracy reference instruments, we compare readings from your volume flow hood with our standard measurements. Any discrepancies are noted and corrected.
4. Adjustment and Certification: Fine-tuned adjustments are made if necessary to ensure alignment with our calibrated reference instruments. A detailed certificate of calibration is provided, confirming the accuracy of your equipment.

Fast Turnaround Time

We pride ourselves on offering a swift turnaround time of approximately three days for our balometer calibration services, minimizing downtime and ensuring you can get back to work promptly with accurate and reliable measurements.
