SigmaCheck Specification and Kit 


The SigmaCheck Eddy Current (ECT) Conductivity Meter from ETher NDE is a truly up-to-the-minute EC Conductivity Meter on the non-destructive testing (NDT) market.

In comparison, the SigmaCheck has many features that far out weigh the competition.

The first thing you will notice when switching on the SigmaCheck is the high resolution, colour, graphic display. The SigmaCheck ET Conductivity Meter is also lightweight, ergonomically designed and boasts a rubber boot for easy grip.

On a more technical level, the SigmaCheck has specification advantages over the competition. These include:

+ More available frequencies (60kHz, 120kHz, 240kHz, 480kHz plus an optional 960kHz)

+ Read out of Coating Thickness and Lift Off

+ Easy to use data logging (emphasis on the "easy to use")

+ USB.R-232

+ Multiple charging options (rechargeable batteries and USB charging)
