When looking for leaks in compressed air piping, be sure to inspect all sides of a pipe or the leak may be missed. Airborne ultrasound is directional. Use a flexible wand sensor for difficult access areas and to reach behind piping that is close to a wall or ceiling corner. For overhead ceiling piping use an extended distance sensor or parabolic dish with laser sighting. Tip Povided by:
