B3C Fuel Solutions DEF contamination test strips — Pack of 100, rapid hydrocarbon detection for DEF tanks

Keep your SCR system running reliably by checking DEF for oil, diesel, gasoline, or other hydrocarbon contaminants before topping off or servicing. These DIP and DETECT strips provide an inexpensive, portable way to verify DEF purity on-site—no lab required. The pack contains 100 individually usable strips, ideal for fleets, maintenance shops, and heavy-equipment operators who need routine screening.

How quickly will I know if DEF is contaminated?

Results are visible within seconds of dipping the strip into the DEF tank, so you can act immediately when contamination appears. The reactive chemistry produces a distinct color change when hydrocarbons are present, making interpretation simple for technicians.

• Immediate visual response—color change appears in seconds
• Single-step testing—dip strip, remove, inspect
• Easy to read without instruments or training
• Suitable for spot checks during fueling or maintenance

What types of contamination can these strips detect?

The strips are formulated to detect a broad range of hydrocarbon contaminants including diesel, lubricating oil, gasoline and other petroleum products that can compromise DEF and SCR components. They identify contamination sources that would otherwise be invisible in routine fluid checks.

• Detects diesel, oil, gasoline, and similar hydrocarbons
• Alerts to contamination that can foul injectors and catalysts
• Helps diagnose cross‑contamination from fuel transfer or storage
• Useful for screening returned or stored DEF before use

How do I use the DIP and DETECT test strips correctly?

Using the strips takes only a few seconds: immerse the reactive pad into the DEF, withdraw, and compare the pad color against the expected clean color. No special tools are required—dispose of each strip after a single use.

• Open package and remove one strip at a time
• Dip reactive pad into DEF and remove immediately
• Inspect for any color change; discard after reading
• Keep strips dry and store at recommended temperatures

How can these test strips help lower maintenance costs?

Early detection of hydrocarbon contamination prevents progressive damage to SCR hardware by allowing targeted cleaning or fluid replacement before parts fail. Regular screening reduces downtime, lowers the chance of costly repairs, and supports compliance with emissions maintenance best practices.

• Catch contamination before it reaches SCR components
• Reduce unplanned downtime from system failures
• Minimize expensive part replacements and labor
• Enable routine checks across a fleet with low per-test cost

Who is this for: maintenance crews, fleet managers, diesel technicians, DEF suppliers, and equipment renters who need fast, reliable contamination screening. The pack of 100 strips is well suited to busy shops or field crews that perform routine checks across multiple vehicles or storage tanks and want a practical, low-cost way to protect SCR systems and maintain DEF quality.
