Harbor Freight launched the Cen-Tech line of products in 2005 to provide high quality, affordable electrical and diagnostic equipment to both automotive professionals as well as part-time mechanics and hobbyists.


Cen-Tech products help diagnose even the most elusive repair problems. These specialty items are designed for the automotive technician as well as the enthusiast or home user. Cen-Tech inspection cameras enable users to view out-of-sight areas and provide streaming video to your PC. Cen-Tech on-board diagnostics readers help evaluate problems by connecting to your vehicle’s computer.

The Cen-Tech line of products are rigorously tested at Harbor Freight Tool's Quality Assurance division in Calabasas, CA, which is dedicated to quality control, product testing, development and improvement. The toughest real-world conditions are simulated in the testing process to push the limits of each product in ways that customers will actually use the tools. Testing is administered throughout the production process and continues through post-production to reduce the possibility of defects as well as improve new model upgrades.

The Cen-Tech brand carries a 90 day warranty when the product is returned to a Harbor Freight Tool store with receipt/proof of purchase. Limitations apply.
