SigmaCheck2 Eddy Current (ECT) Conductivity Meter
The SigmaCheck2 Eddy Current (ECT) Conductivity Meter is designed to provide the user with fast and accurate conductivity measurements at a reasonable price.
The SigmaCheck2 EC Conductivity Meter is extremely easy to use making it suitable for use by shop inspectors or engineers.
The SigmaCheck2 ET Conductivity 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. The SigmaCheck2 Eddy Current Conductivity Meter is also useful to determine the purity of precious metals (counterfeit detection) such as gold bullion and coins.
- Material verification/sorting
- Heat treatment verification
- Heat or fire damage investigation
- Lightning damage investigation
- Determining material purity/composition
- Material ageing assessment
- Measuring phosphor content of Cu Alloys
- Monitoring of deposition process for non ferrous material on a non-ferrous substrate
- Monitoring the condition of highly stressed parts
- Forged/plated material detection
The SigmaCheck2 EC Conductivity Meter has a large, color, LCD display that is easily seen in all lighting conditions.
The SigmaCheck2 is easy to hand-hold due a sculpted housing designed to fit in your hand and a convenient size and weight; only ¾ of a pound (350g) and measuring less than 6 ½” tall x 3 ¼” wide x 1” thick (163 x 80 x 25mm). A removable, silicon rubber boot is included to protect the instrument in rough environments. The standard Probe has been designed to comfortably fit the hand of the user.
The SigmaCheck2 ET Conductivity Meter has a standard operating frequency of 60 kHz and auxiliary frequencies of: 120, 240, 480 and optional 960kHz can be selected when necessary for testing thin materials with the standard probe.
- Field Exchangeable Probes via SD Card
- True USB PC Connectivity for remote control and data logging.
