Certifier 1200

Presenting the industry standard, heavy-duty commercial vehicle test station for complete electrical, air brake, ABS, and 121 brake timing end-of-line testing from LITE-CHECK. With its state-of-the-art software and hardware, many operations are automatically performed and recorded and included in the end-of-line report.



Product Description

Drastically reduce warranty costs and testing time with one tool while increasing customer satisfaction by providing consistent and reliable production and inspection results.

The Certifier 1200 platform features a wireless hub with high-performance wheel sensors, an advanced electronic platform, user-friendly operating system, ergonomic workstation design, and easy-to-read reports.

The Certifier 1200 (powered by 120 VAC) is the best single-solution brake testing equipment for both tractor and trailer brake systems. The Certifier 1200 software takes over routine testing tasks and eliminates operator error while providing reliable reporting. It directly identifies ABS, air-brake, and electrical faults through your 12VDC 7-way round pin-equipped tractor/trailer via the workstation controls and provides full-control from the tablet.

Far more than FMVSS 121 brake timing is under your control, the Certifier 1200 is a complete lighting, air-brake, and ABS tester that automates operations for quick, consistent results. ABS and related end-of-the-line programs come pre-installed. Managers have full control with customizable test procedures and thresholds to meet their organization’s unique needs.

Test reports include advanced electrical, air, and ABS conditions. Photos and notes can be taken and are automatically attached to reports for easy documentation and review.

Product Details
