Thexton Professional DEF-Tester (108)

The Thexton Professional DEF-Tester (108) is an essential tool for maintaining the health and performance of your diesel vehicle. Designed specifically to measure the urea concentration in Diesel Exhaust Fluid (DEF), this tool helps prevent common issues caused by incorrect fluid. Since 2010, most diesel vehicles have been equipped with a DEF tank as part of their Selective Catalytic Reduction (SCR) system. The effectiveness of this system depends on the fluid having a precise urea concentration, typically 32.5%. If the concentration is off, even by a small amount, it can lead to poor performance and potentially cause expensive damage to your vehicle's injectors and catalytic converter. The Thexton DEF-Tester provides a simple, reliable way to verify the fluid's quality, giving you peace of mind and protecting your investment. Its straightforward design makes it easy for both professional technicians and vehicle owners to use.

• Temperature-compensating discs: Ensure precise readings in both hot and cold DEF.
• Clear convex plastic barrel: Magnifies readings for easy and accurate viewing.
• Helps prevent clogged injectors and damage to the catalytic system.
• Simple design suitable for professionals and vehicle owners alike.
