Designed for precise angle measurement on metalwork, this gauge provides absolute and relative angle readings, an upright display, and an audible reminder for quick checks. It uses stainless steel measuring faces to securely attach to any metal surface, giving stable alignment during setup. The large backlit LCD ensures easy reading in varying lighting conditions, even from a distance. An audible alert sounds when the angle is exactly 0 degrees or 90 degrees, helping you confirm square and level without constant monitoring.
