Fluke 88-5 Deluxe Automotive Multimeter

The Fluke 88-5 Deluxe Automotive Multimeter delivers precision electrical diagnostics for conventional and hybrid vehicle systems. With 4.5-digit resolution and 20,000 counts, this meter measures AC/DC voltage to 1000 V, current to 10 A continuous (20 A for 30 seconds), and resistance to 50 MΩ. Purpose-built for automotive technicians, it captures fuel injector pulse width with millisecond resolution, frequency to 200 kHz, and duty cycle percentage. The 10 MΩ input impedance protects vehicle computer circuits from damage.
