Measurements in the ventilation duct
Maintaining the air flows in the ventilation duct is crucial for the function of the ventilation and air conditioning system. If the air flows are lower than planned, the removal of room loads (heating, cooling and material loads) may not be guaranteed under certain circumstances. Therefore, it is particularly important to ensure the most accurate possible measurement of air flows.
Testo offers you numerous measuring instruments that are particularly suitable for measuring in ducts and air conditioning systems.
