RS PRO 130 mm Inclinometer, Magnetic Base Measure the angles of inclined objects with ease using this inclinometer from RS PRO. It offers accurate measurements in all four quadrants, so you can get readings even in hard-to-access positions. The unit has an accuracy of 0.5° to 1°, so it's ideal for general-purpose applications, such as checking the slope of a roof or the incline of a pipe. The base of this inclinometer is magnetic, so you can use it hands-free, without having to worry about it sliding off a surface. Handy rise, run, angle and pitch information on the back of the tool makes it easy to complete trigonometric calculations. There's also a hole on the back where you can attach non-magnetic squares or straight edges using a self-threading screw. This can help you gauge depth in complex shapes quickly. This unit has been tested for quality and reliability. It's typically used in the roofing industry or by carpenters needing to double-check the incline of their table-mounted saws.
