The PosiTector 6000 is a rugged coating thickness gage that uses magnetic and eddy current ideals to easily and precisely measure both ferrous and non-ferrous metals. For most applications, the PosiTector 6000 is ready to measure without any calibration adjustments. These gages are weatherproof - resistant to oil, water, dust, acid, and solvent. The interchangeable platform also allows for any PosiTector probe to attach to a single gage body
