770BXT Electronic Bore Gages with IP67 Protection (with output) .080-12"/2-300MM 770BXT Electronic Internal Micrometers provide IP67 level of protection against coolant, water, dirt and dust in hostile shop environments. In addition, they offer extended travel, reducing the need to exchange anvils. IP Protection An IP number is composed of two numbers, the first referring to protection against solid objects and the second against liquids. First number 6: Totally protected against dust Second number 7: Protection against submersion in water under standardized conditions of pressure for 30 minutes Fea tures • Wide measurement range without changing anvils • Resolution to .00005" (0.001mm) • Large high-contrast LCD digital readout is easy to read and reduces error • RS232, USB, wireless output • Carbide measuring faces on sizes above 1/2" (12.5mm) diameter • Extensions available for deep holes • Includesinstantinch/millimeterconversionandpreset+and-functions • Precision ratchet stop provides correct contact pressure for accurate readings • Each micrometer bore gage with head comes with a wooden case, complete with setting ring, contacts, adjusting wrench, spare battery, and instructions Electronic Bore Gages 770BXTZ-138 780XT Electronic Internal Micrometers, 2-Point Contact (.080-.250" (2-6mm) Range) Cat.
