Use for Calibration  Verification and as a Daily Certified Check Standard

Our copper certified reference material (CS-075) is a true second source to our calibration standards and is very useful as a standard for verification and as a daily certified check standard. It is a good replacement for the BCR® 075 which is now exhausted.

The nominal values in this copper certified reference material are derived from a major U.S. magnet wire manufacturer's material acceptance limits. These low- to mid-range values are very useful for daily certified calibration checks performed by electrolytic primary copper producers, solvent extraction electrowon copper producers, and high purity copper consumers.

Ready to use

Standards and certified reference materials are pickled and pre-cut to custom weights between 250 mg and 500 mg according to customer needs. 

Accurate pre-cut weights provide for very small error bars and relative standard deviations during calibration and daily use.

Accuracy and convenience!
