Compared with traditional inclinometers this product equips 3 pieces of strong magnet so that it can firmly be attached to metal surfaces; In addition the reading is always displayed upright even the inclinometer is upside down; Moreover you can simply place the meter on a reference surface zero to measure relative angle then it will give a result of measured slope angle. With absolute angle measurement you will able to test whether the working surface is on the level. You can use this function to check roof slopes and wheel alignment etc. This meter works great for miter and table saws detailed applications are listed as follows.
