The SigmaCheck Eddy Current Conductivity Meter is designed to provide the user with fast and accurate conductivity measurements at a reasonable price.

The SigmaCheck is extremely easy to use making it suitable for use by shop inspectors or engineers.

The SigmaCheck 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 SigmaCheck is also useful to determine the purity of precious metals (counterfeit detection) such as gold bullion and coins.

Applications for the SigmaCheck:

  • 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 SigmaCheck has a standard operating frequency of 60 kHz and auxiliary frequencies of: 120, 240, 480 and 960kHz can be selected when necessary for testing thin materials with the standard probe.

The SigmaCheck has a large, color, LCD display that is easily seen in all lighting conditions.

The SigmaCheck 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 (163x80x25mm). 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 SigmaCheck is supplied with a carry case (a flame retardant ABS case is also available as an optional extra), a dual (Hi-Low) calibration block, probe cable, charger, USB lead, removable desk stand and user manual. Optional, small diameter probe will be offered. 

Some of the main features of the SigmaCheck include:

  • Field Exchangeable Probes via SD Card
  • True USB PC Connectivity for remote control and data logging.
  • The USB Connection allows easy charging of the Instrument without having to swap the batteries.
