There are four models of TQC destructive Thickness Gauge blades SP1111, SP1112, SP1113, and SP1114 . Each model has a different number of blades and different measurement ranges. They are used to measure the coating thickness of single or multiple substrates, including: wood, plastics , metal, etc. Precision destructive measuring instrument made of titanium and aluminum, mainly used to check and measure the coating thickness of single or multiple substrates (in fact all), including: wood, plastic, metal, etc. Defects in substrates and coatings can also be evaluated and measured. A small incision is made on the Super-PIG recoating, and the incision is measured with the help of an LED illumination microscope measuring grid. Reduce calculations. The unique rotating system contains three stainless steel cutters and a cross cutter.
