Trusted by quality assurance professionals, it offers premium precision without the premium calibration certification cost.

## Description

Size estimation charts are useful in a variety of circumstances for accurately measuring spots, inclusions, and defects on different textile surfaces, paper, plastic, etc. Other brand transparency charts may be imaged using a second generation copy from a master negative. Ours are first generation charts for increased accuracy. Produced on high dimensionally stable lithographic film, .007 stable base polyester photographic film. A densitometer is used to calibrate the imaging equipment as well as a certified hglass scale and an Edmunds scientific 60 power microscope to measure each image. The SEC-01 version of our estimation chart now includes a ruler and other size features.
