Kinematic Viscometer LKV-A17

The Kinematic Viscometer LKV-A17 is optimized for Newtonian fluids, including diesel, gasoline, base oils, lubricants, hydraulic fluids, transformer oils, and other petroleum-based substances. It can also test chemicals with stable viscosity characteristics across the set temperature range. However, it's not recommended for non-Newtonian fluids like emulsions, slurries, or polymer-thickened materials, as their flow behavior doesn't align with standard capillary test methods. Using the correct capillary size and pre-conditioning samples ensures accurate viscosity readings.

Labtron Kinematic Viscometer LKV-A17 requires different capillary tubes depending on the viscosity range of the sample. Lower viscosity fluids need smaller tubes, while higher viscosity samples require wider tubes for proper flow during the timing period. The viscometer supports multiple tube sizes, and users can calibrate each one using standard reference oils. Refer to ASTM or the product manual to choose the correct tube based on your sample type.

The Kinematic Viscometer LKV-A17 allows testing of samples at sub-zero temperatures, with a working range down to –60°C. This feature is useful for checking how fuels and lubricants behave in cold climates or during engine cold starts. The unit uses low-freezing-point bath fluids to maintain stable temperature control. Make sure the correct bath fluid is used to avoid freezing or damage.

Our Kinematic Viscometer LKV-A17 can test up to four samples at once, and each sample is handled separately by the system. One person can easily run and monitor all tests at the same time. The system takes care of timing, measurement, and data recording automatically. This helps improve efficiency without needing extra staff.

Labtron Kinematic Viscometer LKV-A17 should be calibrated regularly to keep test results accurate. Users should verify calibration with standard viscosity fluids weekly or monthly, based on how often the unit is used. For frequent testing, calibration should be done daily or before every batch. The viscometer allows saving calibration data for different tubes, and any unusual result should be checked with a new calibration or by inspecting the system.
