Coating Thickness Gauge TT220 / 230

coating thickness gauge TT220 / 230


Coating thickness gauges are essential to check the exact amount of coating done on your product. A less amount of coating means the coating will wear out in the initial use and more coating layers means it will either crack or spread unevenly giving the surface unbalanced look with some part more glossier than other. Coating is done in most cases to provide a anti corrosion for your products. This instrument checks the layers of coatings on ferrous and non ferrous using eddy and magnetic current. F probe means on ferrous and Probe N is for non ferrous applications. Probe F works on magnetic induction principals and is commonly used for checking insulated coating like paint, enamel and non ferrous coating on ferrous objects. Probe N measures insulating coating on non-ferrous by eddy current method.
