SigmaCheck 2 Eddy Current Conductivity Meter

The Ether NDE SigmaCheck 2 Eddy Current Conductivity Meter is designed to give accurate conductivity measurements while offering the user the very best in reliability, usability, technology and cost-effectiveness. The SigmaCheck 2 is extremely user friendly and can just as easily be operated by a semi-skilled Operator as by Experts. It is equally at home in the Aerospace, Metals Processing, Casting, Maintenance and Quality Assurance industries as well as appealing to Heat Treatment Specialists.
