Smarter Diagnostics. Faster Decisions.

The Inspector 930 is your all-in-one solution for trailer electrical, ABS, and air brake testing. It runs full-system diagnostics on 7-way trailers, identifying shorts, opens, and grounding issues with real-time voltage and amperage readings.

It also handles full ABS testing, reading and clearing fault codes, displaying ECU details, and testing wheel-speed sensors. Built-in air brake testing lets you monitor service and emergency systems at 110–120 PSI, check for leaks, and verify performance in minutes.

Backed by Sentry software compatibility, the Inspector 930 delivers instant results, customizable reports, and complete confidence in your inspections — whether you're doing DOT checks or preventive maintenance.
