Product Description

Charts are useful in a variety of circumstances for accurately measuring spots, inclusions, and defects on different textile surfaces, paper, plastic, etc. Useful in many industries including medical, aviation, printing, optometry and others for quick identification of defects for quality control.

These are high resolution dimensionally accurate QC tools to check for fit, missing holes, and or hardware made from MFG drawings, tools, or your specifications.

Let us help design one for your specific industry. You can provide vector artwork, or we can work with you to design a chart.

Simple design work will be $25, we will custom quote for more intricate needs. You can also send us a part and let us know what you are trying to achieve for measurements and we can assist.
