Summary

Answer
If your turbidity measurements are reported to the USEPA, use a primary turbidity standard such as formazin or StablCal for calibration only. A Cal-Cube is a secondary standard designed for verifying that the calibration of a turbidimeter is correct. It can be used for calibration only if the turbidity values are not being reported to the USEPA.
