This essential workshop accessory helps ensure optimal Selective Catalytic Reduction (SCR) system performance in modern diesel vehicles. The tester uses a simple yet effective floating disc method to determine AdBlue quality. When a sample is added to the robust plastic body, the number of discs that float indicates the fluid's condition, providing a quick visual assessment without the need for electronic equipment or laboratory testing. Clear test procedure instructions are moulded directly onto the body for easy reference during use. Ideal for vehicle workshops, fleet maintenance operations and mobile mechanics working with modern diesel engines, this tester offers a straightforward way to verify AdBlue concentration before topping up or to diagnose potential SCR system issues.
