Fast and Portable Viscosity Testing for Fuel and Lube Oil Verification

In industries where fuel quality affects equipment performance, having an easy and accurate way to verify viscosity is essential. From fuel supply depots to power plants and processing sites, engineers and operators increasingly need on-the-spot verification tools that don’t rely on sending samples to laboratories.

The Heated Viscometer provides a fast, portable solution for testing fuel oil analysis and lube oil analysis directly at the point of use, without the need for conversion tables or complex lab setups. 

It’s especially useful for verifying the consistency of diesel or fuel oil deliveries before they are pumped into tanks or systems - helping operators avoid off-spec deliveries and blending mistakes.

This makes the Heated Viscometer ideal for confirming that delivered fuel meets the required specifications — before it’s pumped into tanks or equipment.

Designed for Field Use - Anywhere

Unlike conventional viscometers that are lab-based, the Heated Viscometer is built for on-site use. Its compact design comes in a rugged case and includes everything needed to run a viscosity test quickly and reliably.

Operators can:

• Perform tests within minutes
• Measure viscosity of fuel oil at 50°C or lube oil viscosity at 40°C, directly - with no need to convert from other temperatures
• Evaluate multiple fuels in succession
• Estimate combustion performance (CCAI) for further insight.

This makes the viscometer a practical tool for anyone needing fast validation of fuel oil quality, whether during delivery, transfer, or storage.

Why Viscosity Matters

Viscosity is more than a number. It defines how well a fuel will flow, atomize, and burn. If the viscosity is too low, it may indicate:

• Fuel dilution
• Contamination
• Shear thinning
• Improper handling or degradation.

All of these issues can lead to poor combustion, carbon build-up, or equipment wear. By catching them early with a quick viscosity check, operators can avoid costly shutdowns or maintenance surprises.

A Better Alternative to Static Fuel Charts

Many engineers rely on fuel specification charts or delivery documentation to estimate viscosity. But charts can’t account for handling issues, contamination, or supply inconsistencies.

With the Heated Viscometer:

• You get a measured value, not a theoretical one
• No guesswork — just a clear result shown on the built-in LED display
• You can test before committing fuel to your system

Typical Use Cases

The Heated Viscometer is commonly used in:

• Fuel oil storage and transfer stations
• Backup power facilities (e.g. diesel generator plants)
• Fuel inspection and compliance operations
• Industrial service teams verifying multiple fuels on-site.

Because of its portability and speed, it’s ideal for technicians who need to test more than one sample in a day, across multiple locations – a perfect fit for onboard oil testing equipment and mobile diagnostics.

Customer Benefits

• Monitors viscosity changes in lube oil, preventing engine and machinery failures
• Verifies that the correct fuel grade or blend has been delivered
• Checks if fuel viscosity is acceptable for storage, pumping, and purifiers
• Provides fast insight into combustion efficiency (CCAI)
• Helps optimize performance in fuel consumption monitoring systems.

"It gives a quick and direct indication of fuel viscosity.

We use it to verify the fuel before pumping — no conversions, no delays."
