SigmaCheck 2
The SigmaCheck 2 Eddy Current (ECT) Conductivity Meter is designed to provide the user with fast and accurate conductivity measurements at a reasonable price; whilst being extremely easy to use making it suitable for use by shop inspectors or engineers.
Meeting the requirements for conductivity measurements in the aircraft manufacture and maintenance, the SigmaCheck 2 is put to work where conductivity measurements are used to verify proper alloy/temper or detect heat damaged components.
The Sigmacheck 2 is extremely user friendly and can just as easily be operated by a semi-skilled Operator as by Experts. It will be equally at home in the Aerospace, Metals Processing, Casting, Maintenance and Quality Assurance industries as well as appealing to Heat Treatment Specialists and those determining the purity of materials such as gold bullion and coins (counterfeit detection).
Procedural Compliance
The SigmaCheck 2 complies with the requirements of the following inspection procedures:
- Boeing BAC5651
- Airbus AITM 6-6004
- ASTM E1004
- AMS2658
- BS EN 2004
- MIL-STD-1537
- Bell Helicopter BPS 4453
Applications Include:
- Material verification / sorting
- Heat treatment verification
- Heat or fire damage investigation
- Material ageing assessment
- Measuring phosphor content of Cu alloys
- Monitoring of deposition process for non-ferrous material on a non-ferrous substrate
- Forged/plated material verification
- Non-conductive coating thickness measurement
- Determining the purity / composition of materials i.e. gold bullion and coins
- Aircraft structures e.g. Paint thickness measurement

Reference Blocks
The conductivity of each reference standard is determined in the central area of the 15mm diameter of the front face by comparison with a similar material, the conductivity of which has been determined in terms of traceable electrical standards.
All supplied blocks are calibrated and the certification of the equipment used in this process is traceable to the National Physics Laboratory (NPL) and the National Institute of Standards and Technology (NIST), and calibrated in accordance with ASTM B193-02.
