The Story
The Bosch GDM600-15 True RMS Digital Multimeter is a professional electrical testing tool designed for accurate, versatile diagnostics on installations, maintenance, and repair work. Built for electricians, HVAC technicians, and maintenance professionals, this digital multimeter measures voltage, current, resistance, continuity, and more in one compact, jobsite-ready tool.
Engineered with True RMS Technology, the GDM600-15 delivers more precise readings when testing standard and complex electrical loads. It supports voltage measurements up to 600V AC/DC, making it a dependable choice for a wide range of residential, commercial, and industrial electrical applications.
A large, high-contrast LCD display improves readability in dimly lit workspaces, while the compact ergonomic design and rubber grip provide comfortable, secure handling during daily use. The integrated kickstand allows convenient hands-free operation, and the meter is also compatible with an optional magnetic hanging solution for added flexibility.
Built for demanding worksites, the GDM600-15 features rubber-reinforced housing that withstands drops up to 6 feet and an IP65 rating for dust-tight and water-resistant durability. Certified to CAT III 600V safety standards, it provides the protection professionals need when working around electrical systems.
For power flexibility, the multimeter operates using the included AA batteries or the optional Bosch GBA37V10 3.7V Lithium-Ion battery sold separately. Power cut-off protection prevents operation when the battery compartment is open, helping reduce the risk of accidental activation. Complete with a tool pouch, MS90 silicone test leads, and batteries, the GDM600-15 is ready for professional use right out of the box
