Duct Averaging with BAPI-Box Crossover

Duct Averaging probes should be used wherever there is a chance for stratified layers of hot and cold air. BAPI Duct Averaging probes are made of bendable aluminum tubing and are able to measure temperature along their entire length. Nylon tie straps are provided for mounting. Duct Averaging Units are available with a J-Box or the new BAPI-Box Crossover Enclosure with green power LED.
