Dropping Point Tester LDPT-A10

The Dropping Point Tester LDPT-A10 is primarily used to test lubricating greases of various consistencies. It is suitable for petroleum-based, synthetic, and specialty greases used in industrial and automotive applications. The standard grease cup and glass tube dimensions allow it to handle most grease samples without requiring customization. However, it is not intended for waxes, oils, or pastes outside of grease specifications.

The Dropping Point Tester LDPT-A10 allows testing of up to three grease samples at a time using three sample indentations. This parallel testing capability helps improve productivity and reduces total test time in high-throughput environments. Each sample is placed in a dedicated test tube and observed individually during the test. This setup is ideal for comparative testing or processing multiple batches efficiently.

Labtron's Dropping Point Tester LDPT-A10 determines the dropping point by heating the grease sample in a standardized cup until it liquefies and a drop falls from the orifice. The temperature at which this first drop falls is recorded as the dropping point. It uses an oil bath to provide controlled and uniform heating throughout the test. A built-in thermometer ensures accurate temperature measurement, while visual observation helps identify the exact moment the drop occurs.

Our Dropping Point Tester LDPT-A10 should be calibrated every 6 to 12 months, depending on the frequency of use. Regular calibration ensures continued accuracy, especially in critical quality control or high-use environments. A certified thermometer can be used to verify the instrument’s temperature readings. Keeping a consistent calibration schedule helps maintain reliable test results over time.

The Dropping Point Tester LDPT-A10 may not produce a drop if there is incorrect sample preparation, impurities in the grease, or insufficient heating. Ensure the grease is properly packed in the cup, the orifice is clear, and the heater is working correctly. Repeating the test with a new sample and checking the oil bath temperature can help resolve the issue. If the problem continues, refer to the troubleshooting section of the user manual for guidance.

Labtron's Dropping Point Tester LDPT-A10 requires caution when operating or cleaning the oil bath. Always allow the unit to cool completely before changing the oil or handling internal parts. Use heat-resistant gloves and avoid overfilling the oil bath to prevent splashing or spillage. Dispose of used oil safely according to local regulations, and routinely check for any signs of leaks or oil degradation.
