The Model AFH2 Air Flow Hood, Balometer is designed to measure volumetric air flow from diffusers, grilles and registers. The AFH2 Air Flow Hood maintains a running average of measurements in the desired units and provides the ability to manually record measurements with the manometer on a given time period. The highly accurate digital manometer has an auto-zero feature and will auto-zero at user-defined intervals. The digital manometer easily mounts to the flow hood with its magnet back-plate. Break down is very quick and easy as tools are not required. In addition to these features, the unit will alert you when its battery is running low in order to avoid recording inaccurate measurements. This lightweight flow hood is durable and easily stores into an included travel case. The AFH2 comes with a calibration certificate for both hood and manometer.
