In any quality control lab that handles petroleum products, lubricating oils, or industrial fluids, there is one question that never changes: Does this fluid flow the way it should? The answer to that question — every single time — starts with a Redwood Viscometer.

Redwood Viscometer

"Viscosity isn't just a number. In a QC lab, it's the difference between a product that performs and one that fails in the field."

What is a Redwood Viscometer?

A Redwood Viscometer is a precision laboratory instrument designed to measure the kinematic viscosity of petroleum products and oils by recording the time in Redwood seconds for a fixed 50 ml volume of fluid to flow through a calibrated orifice at a controlled temperature. It's one of the most trusted methods for oil viscosity testing in both industrial and research environments, and the go-to instrument for IP 70-compliant viscosity measurement.

At Heico Dynamics, we manufacture two variants built to international calibration standards: the Redwood Viscometer No.1, for light, low-viscosity oils (efflux time up to 2000 seconds), and the Redwood Viscometer No. 2 for heavy lubricants, fuel oils, and high-viscosity fluids. Both are engineered for consistent, repeatable results — every test, every shift.

The Case for Viscosity Testing in Every QC Lab

Viscosity is a direct indicator of fluid performance. A lubricating oil that's too thin won't protect engine components under load. A fuel oil that's too thick can clog injectors and disrupt combustion. A bitumen blend with the wrong flow characteristics can compromise road-laying consistency.

For quality control labs across oil refineries, automotive manufacturing, chemical processing, and road construction, viscosity testing equipment isn't optional — it's the frontline of product integrity. And the Redwood Viscometer, with its proven gravity-flow principle and IP 70 compliance, remains the most straightforward and reliable method available for routine lab testing.

Heico Dynamics Insight:

The Redwood working principle is elegantly simple: heat the sample to a specified temperature, open the orifice, and time the flow. The longer the flow time, the higher the viscosity. No complex software. No calibration drift. Just precision physics, every time.

5 Reasons QC Labs Choose Heico Dynamics Redwood Viscometers

  • IP 70 and IS standard compliance. Our viscometers conform to IP 70 test methods, making results directly comparable across international supply chains and audit requirements. Whether your lab is running ASTM checks or BIS-referenced protocols, Heico Dynamics instruments meet the mark.
  • Covers the full viscosity range. With Redwood No. 1 for light petroleum products — kerosene, refined oils, solvents — and Redwood No. 2 for heavy lubricants and fuel oils, one equipment partnership covers your entire product range, no compromises.
  • Digital accuracy with analogue reliability. Our instruments feature digital temperature indicators and regulators with stainless steel electrically heated baths, eliminating manual temperature guesswork — the leading cause of viscosity test errors.
  • Built for lab durability, not just demonstration. Every Heico Dynamics viscometer is built for daily industrial-grade use — not just academic demonstration. Robust stainless steel construction, consistent orifice tolerances, and straightforward maintenance make them a low-cost, long-life asset for any petroleum testing lab.
  • On-site service and technical support. Heico Dynamics doesn't just deliver equipment. Our service teams provide onsite commissioning, calibration support, and remote technical assistance — so your lab stays operational, not waiting on a service ticket.

Who Needs a Redwood Viscometer?

The answer is broad. Petroleum refineries use it for product release testing. Automotive and lubricant manufacturers rely on it for formulation quality control. Road-construction labs use Redwood No. 2 to test bitumen and cutback asphalts. Chemical QC labs use it to verify fluid consistency in production batches. And research institutions rely on it to establish baseline viscosity data for new fuel blends and industrial oils.

If your lab tests any fluid where flow behaviour determines performance, you need a Redwood Viscometer on your bench.

The Heico Dynamics Difference

As India's trusted manufacturer of laboratory viscosity testing equipment, Heico Dynamics brings decades of engineering precision to every instrument we build. Our Redwood Viscometers are calibrated to international standards, designed for the demands of real QC environments, and backed by the technical support network that modern labs require.

Quality control is only as reliable as the instruments behind it. Make sure yours are built by people who understand what accurate viscosity measurement actually means on the lab floor.
