DFYF-108D Petroleum Product Kinematic Viscosity Tester

2026-05-12

GB/T 265 & SH/T 265 Compliant | Ambient to –70°C | Dual Test Positions

Low-temperature kinematic viscosity is a critical quality indicator for diesel fuels, aviation kerosene, lubricants, and other petroleum products. The DFYF-108D delivers reliable, standard-driven measurements with a powerful low-temperature bath and simple operation.

✅ What Makes the DFYF-108D Stand Out?

Split-type construction – The refrigeration unit is separated from the bath section, minimizing vibration interference during viscosity measurement. This design also improves heat dissipation and extends compressor life.

Imported compressor – Delivers rapid cooling down to –70°C with high stability and long service life. No more waiting hours for bath stabilization.

Dewar flask alcohol bath – Excellent thermal insulation and visual clarity. The double-layered Dewar flask maintains uniform low temperatures while allowing easy observation of capillary viscometers.

Dual test positions – Run two samples simultaneously, doubling your testing efficiency without compromising temperature uniformity.

Smart digital temperature controller – Clear LED display, ±0.1°C precision, and intuitive setting for different test temperatures.




�� How It Works (Simple Workflow)

Fill the Dewar bath with alcohol (or appropriate cooling medium).

Set the desired test temperature (e.g., –20°C for diesel fuels).

Place two capillary viscometers with samples into the bath.

After temperature stabilization, measure the flow time manually or with an external timer – then calculate kinematic viscosity according to GB/T 265.

The DFYF-108D removes the guesswork from low-temperature viscosity testing, giving you repeatable results for product development, QC, and export certification.




�� Who Should Use This Instrument?

Fuel and lubricant refineries

Third-party testing laboratories

Aviation fuel (Jet A, Jet A-1) QC labs

Diesel and heating oil manufacturers

Automotive oil R&D centers




❄️ Designed for Critical Low-Temp Applications

Many petroleum products must maintain adequate fluidity at subzero conditions. The DFYF-108D helps you verify:

Kinematic viscosity of diesel fuels at low temperatures (cold filter plugging point correlation)

Aviation fuel viscosity at –20°C or –40°C

Low-temperature performance of hydraulic oils and gear oils




�� Beyond This Model – Redefining Viscosity Testing

While the DFYF-108D focuses on reliable, standard-compliant low-temperature viscosity measurement, our engineering team is also pushing boundaries in automation.
