Existent Gum Tester LEGT- B30 : Oil bathLabtron Existent Gum Tester evaluates physical properties of gum samples. Their advanced sensors provide real-time feedback on elasticity and viscosity during testing processes. They incorporate temperature control system to maintain optimal conditions during procedure. Their automated data logging capabilities streamline record-keeping, enhancing traceability and compliance efforts significantly. Our Existent Gum Tester is utilized in food industry, pharmaceuticals, materials science, quality assurance, and consumer research to ensure product quality in chewing gum.



Labtron’s Existent Gum Tester LEGT-B30 requires fuel samples to be filtered before testing to remove particulates that may affect results. Fill the sample container to the marked level and ensure it is securely positioned in the evaporating bath. Preheat the unit to the specified temperature based on the fuel type, typically between 150?°C and 250?°C. Always use proper safety equipment like gloves and goggles when handling flammable fuels.
Labtron Existent Gum Tester LEGT-B30 is suitable for testing aviation gasoline and jet fuels in accordance with ASTM D381 standards. For jet fuels requiring precise temperatures around 160–165?°C, careful calibration of the device is essential. Always confirm the specific requirements of the test method before using aviation-grade samples. Our gum tester offers a practical option for basic jet fuel testing needs in standard lab settings.
The Existent Gum Tester LEGT-B30 is designed for single-sample testing, making it ideal for small laboratories or quality control setups with low testing volume. This unit does not support multiple sample positions. The single-sample configuration simplifies handling and cleaning while maintaining precision. Our tester is best suited for labs prioritizing focused, accurate testing.
The Existent Gum Tester LEGT-B30 may show temperature instability if the heating element is faulty or the thermostat is not functioning correctly. Check that the oil level in the bath is within the recommended range, as low oil can cause uneven heat distribution. Also, confirm that the power supply is stable and not experiencing overload. Refer to the user manual or contact our support team if the issue persists.
Labtron’s Existent Gum Tester LEGT-B30 may produce high gum values if the fuel sample is contaminated, improperly stored, or aged. Confirm that the test conditions particularly the bath temperature and vessel cleanliness are correct. High gum levels can also indicate oxidation or degradation of the fuel itself. If consistent abnormalities appear, inspect the equipment for calibration issues or uneven heating.
Our Existent Gum Tester LEGT-B30 requires regular maintenance for reliable long-term performance. This includes cleaning the oil bath, checking electrical wiring, and replacing worn components such as seals or heating elements. The temperature control system should be calibrated periodically to maintain accuracy. Storing the unit in a dry, dust-free environment also helps prevent wear and prolongs equipment life.
