AVT

Air velocity and temperature transducer with 3 selectable ranges engineered for building automation in the HVAC/R industry measuring air velocity and temperature in ducts for fancoil, valve and electric heater applications. Optionally, an LCD as well as realy outputs for limiting and monitoring are available.
