Kinematic Viscometer LKV-A12

The Kinematic Viscometer LKV-A12 is equipped with 11 capillary tubes, enabling it to measure a wide range of viscosities from low-viscosity fuels to high-viscosity lubricating oils. Users can select the appropriate tube based on the expected resistance of the fluid. This variety ensures reliable results across many applications. It is well-suited for laboratories that handle diverse sample types.

Labtron's Kinematic Viscometer LKV-A12 is designed to measure both transparent and opaque liquids efficiently. As long as the liquid flows properly through the capillary tube and timing can be observed or calculated, accurate viscosity readings are achievable. For very dark samples, enhanced lighting or alternate timing techniques may be used. The instrument supports such fluids in accordance with ASTM standards.

Our Kinematic Viscometer LKV-A12 includes a range of capillary tubes with varying diameters and calibration constants to suit different viscosity levels. Selecting the right tube depends on the expected viscosity and target flow time typically between 200 and 1000 seconds for optimal results. Start with manufacturer guidelines or previous lab data, then fine-tune based on sample behavior. Using an improperly sized tube can reduce measurement precision and consistency.

Labtron Kinematic Viscometer LKV-A12 requires thermal equilibrium for accurate readings, so allow sufficient time for the bath to stabilize. If discrepancies persist, ensure the external thermometer is positioned properly within the bath for comparison. Calibration drift of the internal sensor may require adjustment or recalibration. Always verify temperature alignment before performing high-precision tests.

Our Kinematic Viscometer LKV-A12 is highly sensitive to the sample’s viscosity and flow characteristics. If a fluid does not flow or flows too slowly, try switching to a larger-diameter tube or pre-warming the sample to reduce viscosity. Make sure there are no air bubbles or blockages inside the tube. Filtration may be necessary for samples containing particulates.

Labtron's Kinematic Viscometer LKV-A12 uses a water bath, minimizing ignition risks during viscosity testing of flammable liquids. Still, it’s essential to operate the device in a well-ventilated lab and avoid open flames or spark-producing devices nearby. Use sealed tubes if required and follow safety instructions. Never leave the equipment unattended when testing volatile samples.
