ELOTEST M2 

Ergonomic One-Hand Eddy Current Test Instrument 

The ELOTEST M2 is a universal one-hand tester for surfaces, drill holes and hidden structures. It also measures the conductivity and layer thickness of all materials. The ELOTEST M2 allows a DUAL frequency test with mix and covers the complete range of frequency from 10 Hz to 12 MHz. It offers a signal optimization for static and dynamic tests due to all filter functions (LP, HP, BP ). The sharp LCD Display with LED illumination ensures an optimal visibility of the test signals, even in direct sunlight. Integrated calibration bodies simplify and accelerate on-site work. The device is operated with a well-structured keypad and clearly assigned functions. This allows even unexperienced users to work with quickly and safely. The user-friendliness is supported by clear text messages on the screen.
