How does the anvil impact force of the PosiTector RTR compare to that of spring micrometers?
They are the same. Mitutoyo micrometers supplied by Testex have had special modifications made to their springs and anvils. The PosiTector RTR has the same anvil size (0.25 inch / 6.25mm diameter) and applies the same spring tension (110 gram‐force / 1.1 Newtons) as Testex micrometers and as required by major test standards.
