Air conditioning & ventilation technology

    Inspection of filters

    HVAC systems are always used when a constant indoor climate must be guaranteed - such as in production buildings or cleanrooms. HVAC systems are subject to strict hygiene regulations, and air filter monitoring and testing is a high priority.

    The instrument calculates the differential pressure via a measurement upstream and downstream of the filter. This provides information on the degree of contamination of the filter. With the differential pressure measuring instruments from Testo, you can quickly and easily determine whether a filter is dirty.
