Pressure and air flow

Air pressure has an obvious impact on HVAC system performance. Testo offers a range of instruments to help technicians measure this factor. Differential and absolute pressure have different consequences, which is why we've developed tools to help you calculate each variable.Best of all, our instruments enable professionals to compare pressure with airflow and velocity through a single interface.


Did you Know: The Testo 510i can measure gasflow, static pressure as well as volume flow and transfer all the data to your smartphone.
