MINITEST 70
MİNİTEST 70
The MiniTest 70 enables non-destructive measurement of non-magnetic coatings (paint, synthetic material, chrome, etc.) on a ferromagnetic substrate (steel) and insulating coatings (lacquer, enamel, synthetic material, etc.) on conductive substrates (aluminium, copper, austenitic stainless steel).
The spring-mounted sensors are equipped with wear-resistant sensor poles to give especially high durability also when measuring abrasive substrates.
MiniTest 70: Coating thickness measurement in a practical pen format
MiniTest 70 is a lightweight and practical coating thickness measurement gauge in pen format with inbuilt sensors. It comes with several benefits:
- Precise measurement of coating thickness up to 3mm (F) or 2.5mm (N)
- A dual sensor automatically identifies the substrate and sets the appropriate measuring procedure: eddy currents or magnet-inductive (excluding model E)
- Wear-resistant probes for long service
- Weighs only 80 grams
