Dropping Point Tester (Air bath) LDPT-A11 Catalog
Labtron Dropping Point Tester features a heat-resistant beaker, designed to withstand high temperatures for safe and reliable operation. They come with a high-quality heater, ensuring efficient and consistent heating performance. Their high-speed electric motor drives rapid and smooth operation for improved productivity. These desktop structures controlled by bidirectional silicon-controlled rectifiers, offer precise control over the system's performance. Our dropping point tester features a double sample working style, allowing for increased efficiency by testing two samples simultaneously.

Labtron Dropping Point Tester (Air bath) LDPT-A11 uses SCR-based control to manage temperature precisely by adjusting power to the heating elements in real time. This helps avoid sudden temperature spikes and keeps the heating process stable. The SCR system also lasts longer and uses less energy compared to older relay-based controllers. Our design ensures better temperature consistency and reliable results in every test.
The Dropping Point Tester (Air bath) LDPT-A11 typically uses glass mercury or alcohol thermometers calibrated in °C, designed specifically for dropping point testing. The thermometer is inserted vertically into a support stand so that its bulb is aligned closely with the sample cup without touching it. Proper alignment ensures accurate temperature tracking of the surrounding air inside the furnace. Users must verify that the thermometer scale matches the required measurement range (usually up to 300?°C) and is free of any air bubbles or breaks in the mercury/alcohol column.
Labtron Dropping Point Tester (Air bath) LDPT-A11 uses an air bath, which makes testing cleaner and easier to maintain since there is no oil involved. There is no risk of oil spills or smoke, and the equipment stays cleaner over time. The air bath also cools down faster after use and avoids problems like oil breakdown or sticky buildup. It is a good choice for labs that want simple operation without dealing with heated oils.
Our Dropping Point Tester (Air bath) LDPT-A11 gives best results when the grease is packed evenly in the cup and the thermometer is placed properly. Make sure the heating is steady in both sample zones, and keep the room free from strong air movements or vibrations. Let the tester cool down fully between runs to keep conditions the same each time. If differences continue, check the heating parts or recheck the thermometer position.
The Dropping Point Tester (Air bath) LDPT-A11 should be kept clean by removing any leftover grease or burnt material from the furnace and sample areas. Check the electrical parts like heating wires and SCR units now and then to look for signs of damage or heat stress. Don’t use metal tools that could scratch or harm the inside parts. It should be used only within the specified ambient temperature and humidity range to prevent damage and maintain long-term performance.
