Product Overview: PHASE ‖ PTG-3550 series of thickness using eddy current and magnetic induction principle to be completed by measuring the thickness of two ways. Two non-destructive measurement methods are very accurate. Unmatched by the two arbitrary thickness, you can easily use the built-in sensor type or sensor type to detect external magnetic substrates (iron based) or non-magnetic coatings on non-magnetic matrix (non-iron based) on the insulator. PHASE ‖ PTG-3550 suitable for many industrial fields such as manufacturing, general engineering, chemical inspection. PTG-3550 automatic identification using an external probe iron-based or non-ferrous base and is equipped with two substrate samples (steel, aluminum), 4 the thickness of the calibration test block, equipment boxes, batteries and operating manual.
