Tank Truck Overfill Prevention System Diagnostics

**THE UNIVERSAL TRUCK TESTER WILL NO LONGER BE AVAILABLE FOR PURCHASE AFTER AUGUST 26, 2025. Instead, check out our HazLoc Approved Mobile Truck Tester Kit & App.**

The Scully Universal Truck Tester is the most comprehensive road tanker tester available. It checks the operation of road tanker overfill prevention and self-proving grounding (earthing) systems. Complete diagnostics limit the expense of downtime.

The tester is compatible with Scully Intellicheck®, Load Anywhere®, and independent Scully optic and thermistor road tanker sensors. Once the tester is set up in a non-hazardous area, move the selector switch to the desired setting and connect the tester to the tank truck socket with the appropriate plug and cable. The test results will be shown clearly on the easy-to-read LED display.
