Scully Signal Company has obtained approval for the Mobile Truck Tester (MTT) to be used in Hazardous Environments—a feature required when used in loading lanes of petroleum terminals, and in many global regions. The accompanying user-friendly app received upgrades as well, with new functionality including test report generation, backup and restore capability, and global real-time clock adjustments among several other enhancements.
The MTT provides an intuitive, single-operator solution for troubleshooting and validating tank truck overfill, grounding, and vehicle identification systems prior to loading.
Some key capabilities of Scully’s Mobile Truck Tester include:
• Comprehensive testing for overfill, ground verification, and truck identification systems.
• Versatility making it ideal for tank truck carriers, independent repair shops, and terminal managers.
• Single person operation allows users the ability to conduct wet tests solo with a phone or tablet.
• Truck ID is easily accessible available on the tester or the app.
• Single sensor or sensor holder testing through the socket adapter and wire harness.
When paired with the app, the MTT offers added automation to streamline troubleshooting, documentation, and maintenance. Key app capabilities include:
• Test Report Results: A simple table of single or aggregated test results that can be shared.
• Archive Test Results: Store test logs per truck ID, customer, or work order for historical reference.
• Advance Fault Notifications: Detailed failure modes are listed during wet test, allowing for quick repairs.
• User-Friendly Digital Application: The first-of-its-kind application in the industry is intuitive, easy to use, and supported on IOS and Android devices.
Dani Alkalay, director of product marketing at Scully, says: ‘The Mobile Truck Tester has been widely adopted by repair shops and fleet technicians because it is simple, ergonomic, and built for true single-person operation. Achieving hazardous area approval opens new opportunities for use at petroleum terminals and other global facilities requiring these safety standards.’
The MTT Kit expands Scully’s portfolio of overfill prevention and safety technologies and continues the company’s 90-year legacy of engineering innovation.
