WeldCheck 3
The WeldCheck 3 is a dual-frequency eddy current inspection instrument with conductivity. Dual channel/ frequency capability means that the instrument can be used for dual and single frequency applications.
The Flaw detector is ideal and adaptable across an extremely wide variety of eddy current inspection tasks due to its superior performance; including weld inspection, surface defect detection and low frequency inspection of non-ferrous material.
The WeldCheck 3 Series now offers the option of two models, one with the standard keypad for instrument navigation and the other with a thumbwheel configuration for fast single-handed software navigation, phase and gain adjustment during inspection.
Equipped for all environments The WeldCheck 3 is going to come up against some of the harshest working conditions in the NDT industry, not to mention being lifted and lowered on ropes, dropped and bumped.
The WeldCheck 3 has a fully daylight readable 14.5cm LCD Colour Screen of 640 x 480 pixels ensuring the operator has crisp presentation no matter what the working conditions are.
