Brystar Tools provides quality accessories for your portable hardness testing needs. We have a full selection of impact devices that are useful for many different applications. Our selection includes D, DL, D+15, DC, C, and G impact devices. The D device is an universal standard unit that will handle the majority of hardness testing applications. The DL is used suitable for testing in extremely confined spaces such as the base of grooves and on special components which include gears. The D+15 device is for very narrow areas. The measurement coil is set back to provide more clearance for steps and holes. The DC model is a short version of the D device and was designed for confined areas like the inside walls of thick-wall pipes that the other devices won't fit in. The C version applies a superficial indentation and is a reduced impact energy probe (2 ft-lb) for measuring hardness of coatings, surface hardened, thin wall or impact sensitive components. The G impact device that was designed for components like heavy castings and forgings with lower quality finishes measuring in the Brinell range only (max. 650 HB). The tip is enlarged and has about 9 times the impact energy as the D device. Is the Leeb test block that came with your tester full of indents and in need of replacement? We offer a nice assortment of blocks for you to choose from.. Look over our selection of accessories available from Brystar Tools. The choice is yours. Buy here.
