Why FuelGuard exists
Fuel risk becomes expensive when evidence starts too late.
Contaminated or adulterated fuel can trigger downtime, injector and pump failures, supplier disputes, maintenance uncertainty and insurance complications. FuelGuard moves the control point forward—before the vehicle or equipment continues.
- Test at the operational point of risk
- Record who, where, when and what was supplied
- Retain photographic and transaction evidence
- Escalate anomalous results for confirmatory analysis
Featured innovation
Every refuel tested. Every result recorded.
DensiTest is being developed around the operational reality of fleets: a driver needs a fast, clear procedure that creates evidence without turning every refuel into a laboratory exercise.
- Compulsory rapid test before departure
- Vehicle, driver, supplier, GPS and timestamp linkage
- Odometer, litres, price, receipt and test-photo evidence
Rapid field screening
DensiTest
A clear, repeatable control step for diesel refuelling events—designed to be tested, photographed, geolocated and recorded before the vehicle continues.
A repeatable control method
From suspicion to a defensible decision.
FuelGuard products work best when embedded in a defined standard operating procedure—not used as isolated gadgets.
Test
Use the approved field method at the defined control point.
Record
Capture the required event, supplier, vehicle and photo evidence.
Verify
Compare results with the expected range and operating rules.
Escalate
Quarantine risk and obtain confirmatory laboratory analysis when required.
Built for fuel-intensive operations
One control objective. Different operating realities.
FuelGuard adapts the evidence requirement, training level and test frequency to the operating environment—while keeping the integrity standard clear.
Discuss Your ApplicationTransport & logistics
Control every diesel refuel, detect anomalies and strengthen supplier accountability.
Fuel wholesalers
Strengthen receiving, dispatch, dispute and customer-assurance procedures.
Storage depots
Integrate sampling, density checks and water-control into depot operations.
Mining & agriculture
Protect high-value equipment operating far from immediate technical support.
FuelCheck Fleet integration
The digital evidence layer behind the field test.
FuelCheck Fleet is planned as the software layer that links the driver, vehicle, supplier, GPS location, timestamp, odometer, litres, price, receipt and DensiTest result into one chain-of-custody record.
Core proposition: Every refuel is tested, photographed, geolocated and recorded before the vehicle continues.

Operational assurance
Tools are only credible when their limitations are clear.
FuelGuard separates field screening from formal laboratory confirmation. Our products support earlier detection, consistent evidence and better operational decisions; they do not replace accredited analysis where legal, insurance or contractual confirmation is required.
Screen
Fast operational signal at the point of risk.
Confirm
Accredited laboratory analysis when certainty is required.

Build fuel integrity into the operation—not into the post-incident report.
Start with the right field equipment, a clear operating procedure and an evidence standard your team can actually follow.
