Why doesn't the microtrack display accuracy?

There is no absolute scale for powders.

There is no absolute scale for powders, and Microtrack does not provide accuracy specifications. One reason for this is that accuracy is generally associated with measurements of length, pressure, temperature, voltage, etc., where an absolute scale exists. However, for powders, there is no absolute scale due to factors such as sample extraction, differences between production lots, sample oxidation, agglomeration, aging changes, and shape factors. For example, particularly with latex, the particle state changes due to environmental conditions, including aging. For this reason, Microtrack does not provide accuracy specifications. "NIST" also does not provide accuracy specifications. In terms of pricing related to various scales, "NIST" is recognized as an authoritative institution worldwide and serves as the basis for traceability. Here too, regarding powders, accuracy specifications are not provided, and the particle size and particle size distribution of standard samples are expressed by indicating the degree of variation in measurement results from sample extraction using methods such as microscopy and natural sedimentation. *For more details, please refer to the related links or feel free to contact us.*
