Velocity

HVAC systems depend on ventilation to cool and heat indoor environments. Moderate fluctuations in airflow and velocity can hinder an HVAC system's efficiency, thereby increasing the costs associated with running such appliances.
Testo's range of airflow and velocity instruments help HVAC technicians assess systems for potential problems. Our digital anemometers can enlighten you to detect problems in facilities and equipment.

While airflow may seem like a negligible factor, improper velocity can compromise indoor air quality, increase utility expenses, cause heat exchanger failures and introduce a wide array of other problems. The parameters dictated at the appliance may not correspond with the velocity present at intake and outflow vents, and Testo's instruments can ensure this consistency.
 
Testo also offers a range of Pitot tubes that allow professionals to measure velocity and airflow. Manufactured with stainless steel, these extensions can withstand the rigours of various environments and are needed attachments for many of our instruments.
If you'd like to know which testo instruments these pitot tubes can complement, speak with one of our knowledgeable experts today.
 
Did you know: Testo Anemometers are sensitive and accurate enough to measure the air current generated by the fluttering of butterfly wings!
