J Chadwick Co.

Many specifications, standards and technical publications have established maximum limits for the depth of surface damage, but the methods commonly used for measuring the damage (usually a pit gage or fingernail) are unprecise and inadequate. The result is that every day parts are sent to the scrap pile for no other reason than lack of a suitable inspection tool.

There is an opportunity to save resources by providing a guesswork-free method to determine if surface damage is within repairable limits to maximize part life cycles and reduce unnecessary replacement. Safety can also be increased by preventing parts with damage that exceeds limits from returning to service because of invalid inspections.

J Chadwick Co’s 8400K Optical Depth Micrometer is a hand-held inspection microscope specifically designed for measuring the depth of surface damage (like scratches, chattering and pitting). The tool is durable, portable, effective, and extremely easy to use. It often paying for itself many times over by saving just one part, making it highly cost efficient with an excellent ROI.

Save resources without sacrificing readiness. If you have maximum limits for surface damage and no reliable method for depth measurements, we can save you both time and parts.
