Longacre Basic Tire Durometer NKA high-carbon alloy discsThe Longacre Basic Durometer measures changes in tire hardness so you can keep track of this important information. Using the Shore A scale, the durometer reads from 0 100 points. A straight edge on the base of the durometer allows the user to rock the gauge for more consistant results. Non slip coating on the back gives better grip for even more accurate readings. Includes hard plastic case.
