Calibration & Repairs

Associated Instruments Repairs have an in-house dedicated Wind Tunnel Laboratory, equipped with two wind tunnels, one for calibrating Balometers and Capture Hoods, and the other is used for calibrating Anemometers and Pitot Tubes. Equipped with the latest test equipment, readings obtained are corrected for the environmental conditions on the day.

We can test, calibrate and repair Vane Anemometers, Thermal Anemometers, Micromanometers, Balometers, Capture Hoods, Thermometers, Tachometers, Temperature Humidity Meters, Velocity ranges on Micromanometers and other Pressure Measuring Instruments.

Calibration Traceability to National Standards is achieved using a TT Series Micromanometer to measure a differential pressure across various Orifice Plates and/or using a Volume Flow Measuring section manufactured in accordance with the ISO 5801: 1997 specification.

For any calibration or repair of your instruments, please complete the on-line quotation form or contact us by email or telephone.
