The AF1 series is an inexpensive, highly accurate and stable transmitter for the measurement of air velocity and temperature. The devices are equipped with a calorimetric sensor and boast outstanding long-term stability. The measure- ment range and output signal can be set easily without additional software via dip switches.
Applications
Laminar flow cabinets, HVAC systems, cleanrooms, monitoring of air con- sumption.
