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.
The SigmaCheck 2 meets the requirements for conductivity measurements in the Aircraft manufacture and maintenance fields, where conductivity measurements are used to verify proper alloy/ temper or detect heat damaged components. It is also useful to determine the purity of precious metals or whether they are counterfeit. It is equally at home in the Aerospace, Metals Processing, Casting, Maintenance and Quality Assurance industries as well as appealing to Heat Treatment Specialists.
Product Update – The SigmaCheck2 (KISIG001A) has been upgraded to the SigmaCheck2 (KISIG001B). The new SigmaCheck2 has an updated probe map design, upgraded PCB Board, increased battery life with NEW built-in lithium ion battery, and an improved setup calibration block design. (12/2023)
