HVAC & LEV equipment - air speed calibration

Labcal provides expert single or multi-point calibration and adjustment for air speed and velocity sensors, probes and anemometers including integrated or hand displays used within the HVAC industry and for assessing local exhaust ventilation (LEV)


Typical HVAC & LEV instrument calibration range 0.1 m/s to 30 m/s

Labcal provides expert, independent equipment calibration services to customers within the heating, ventilation and air conditioning (HVAC) industry and to customers who calibrate equipment used for assessing air flows within fume cupboards, extraction hoods or other forms of LEV. We can be found on the UKAS website, laboratory number 0625 – see our schedule here. Please get in touch to discuss your calibration requirements.

Labcal is equipped with four wind tunnels for air speed and velocity calibration which means we can accommodate a wide range of instruments. Additionally we offer the option of laser Doppler anemometer (LDA) calibration which provides air velocity measurement at very low uncertainties.

The Labcal team has the knowledge and experience to calibrate the latest devices right through to instruments that may be many decades old. Here are some devices and manufacturers that we calibrate regularly.

  • Vane anemometers
  • Hotwire anemometers
  • Pitot tubes
  • Testo
  • TSI
  • Air flow
  • Kestrel
  • ATP
  • RS
  • Dwyer
  • Fluke
