series sah smart air hood balancing instrument
quad flow design technology, predictive balancing
now available! sah-22hc with hard travel case!
the series sah smart air hood balancing instrument is the most accurate and easy to operate air flow hood on the market. By using the included hood stand and wireless communications to the handheld, a single operator can balance a branch in less time than traditional balancing teams. Besides being lighter than most traditional capture hoods, the ergonomic design makes the series sah easy to maneuver, with less physical stress. The rugged polypropylene base hood features quad flow design technology for controlling air flow and minimizing back pressure, which yields superior measurement accuracy. The wi-fi direct communication gives reliable communication with a distance of up to 200 yards (183 m) between the hood and the handheld test instrument. The smart air hood balancing instrument includes the predictair application software which reduces the number of steps in the air flow balancing process using predictive balancings express balance mode. Predictive balancing is a method of predicting the optimal flow set point for each register and the order in which they should be adjusted.
note: for full functionality and versatility, the a-sah-12p is required for operation of all sah models.
