AUT500: 14 Function Automotive Digital Multimeter
Automotive Multimeter with Temperature, RPM, Dwell Angle, Duty Cycle and Pulse Width. The Extech AUT500 Automotive Multimeter was designed specifically for automotive technicians, DIYers, and modders who demand a tough meter that’s waterproof and shock resistant. The AUT500 Automotive MultiMeter delivers every multimeter function you need to effectively troubleshoot automotive and fleet electrical and electronic systems. Designed to withstand harsh environments and usage, the meter’s rugged, double-molded housing is IP67-rated (waterproof and dustproof) as well as drop-tested to 6 feet. For shade-tree mechanics or crews doing roadside fleet repairs, using a DMM outdoors during harsh conditions is no longer a concern no matter the weather. Includes the AUT500 Automotive MultiMeter; double-molded test leads; inductive pickup; type K bead wire temperature probe; magnetic hanging strap; 9-volt battery; hard carrying case; operating instructions.
