The new coating thickness gauges MiniTest 2500 and MiniTest 4500 combine high-precision modern measurement technology with classic processing concepts. Two models: MiniTest 2500- basic model with memory and USB output, and MiniTest 4500- adding batch processing memory, Bluetooth, RS232, etc. The MiniTest 2500 and MiniTest 4500 coating thickness gauges measure the specifications non destructively based on the type of sensor connected, using magnetic induction or eddy current principles. Portable measuring instruments are used for fast and accurate non-destructive coating thickness measurement in the field of industrial corrosion protection, and are used by manufacturers and end-users of corrosion protection products, authoritative institutions and inspectors, electroplating and painting workshops, and chemical drugs. Widely used in industry, automobile production, shipbuilding, aviation, as well as tool and mechanical engineering. The MiniTest coating thickness gauge has a particularly sturdy housing with a protection level of IP65, making it equally suitable for laboratory and harsh industrial environments or construction site instruments.
