This change will be a flow-in. As the inventory of the current scales are depleted, AATCC will transition to the newer version. AATCC cannot accommodate product requests but rest assured that the performance and functionality remain unchanged regardless of the version you receive.

Dashes & Dots

AATCC is in the process of transitioning from Dashes to Dots. Some AATCC Gray Scales may have half steps expressed in dashes (-), while others have dots (.) Either is acceptable and usability is comparable. AATCC cannot grant requests for one version over the other. Once all inventory of Dashes are depleted AAATCC will fully convert to Dots. For mathematical calculation, a decimal representation works with most applications. If you have a dash scale simply convert to decimal when inputting details into a mathematical based application.
