QNix1200 and QNix1500 both of these models integrated design, simply zero without calibration, using an extremely simple. QNix1200 magnetic thickness gauge, steel can be used to measure the iron coatings on magnetic substrates, coating; QNix1500 dual-use magnetic and Eddy current thickness gauge, not only can be used to measure magnetic substrate, such as steel, can also be used to measure the aluminum, copper, stainless steel, non-magnetic metal surface coating, oxide films, coatings such as phosphating film. Both models easy to operate, easy to carry, high precision probe and the fuselage into a 90 ° right angle design, can meet some narrow space (such as the pipe wall) measure favoured by the majority of users.
