SL-ND21A Fully Automatic Kinematic Viscometer Introduction: The fully automatic motion viscosity meter has PTC sample intelligent preheating function, which can automatically control the preheating temperature according to the preset test target temperature of the tested sample. The preheating temperature range is between room temperature and 120 ℃; The preheating rate is 15 ℃/minute, which greatly reduces the constant temperature time of the sample during testing. characteristic: 1. Configure a 16 bit sample tray that can work continuously 24 hours a day. The sample intelligent preheating, injection, measurement, cleaning, drying, result calculation, and repeatability calculation are all automatically completed. 2. Using photoelectric or thermal detection, transparent and opaque samples can be measured, including Newtonian fluids such as gasoline, diesel, kerosene, cutting fluid, heat transfer oil, additives, new lubricating oil, and in use oil. 3. Equipped with PTC sample intelligent preheating function, it can automatically control the preheating temperature according to the preset test target temperature of the tested sample, with a preheating temperature range between room temperature and 120 ℃; The preheating rate is 15 ℃/minute, which greatly reduces the constant temperature time of the sample during testing. 4. Equipped with a Peltier refrigeration system, the constant temperature bath liquid is directly used as the refrigerant to rapidly cool down. 5. Apply bath liquid level adaptive balance technology (patent number: ZL 2020 2 1531117. X) to adapt to large-span temperature adjustment during testing. During the temperature rise and fall process, automatically increase or decrease the constant temperature medium to maintain the immersion depth of the viscosity tube unchanged. 6. Windows operating system, fully Chinese interface, simple operation, user-friendly human-machine interface, can be connected to LIMS system, can be connected to an external barcode scanner, and automatically input sample information. 7. The system comes with an automatic calibration function for viscosity constants, as well as auxiliary functions such as temperature calibration, internal clock timing calibration, automatic conversion of kinematic viscosity to intrinsic viscosity, and automatic calculation of viscosity index. 8. It has dual functions of software and hardware over temperature protection, over temperature alarm, anti dry burning protection, lack of cleaning solution prompt, waste liquid cleaning prompt, etc., to ensure the safe operation of the instrument. 9. Adopting a double-layer glass bath design, PT1000 high-precision temperature sensor, and double blade stirring, the temperature of the constant temperature bath is stable and accurate, with a temperature control accuracy of 0.005 ℃. 10. Use precise algorithms for sample suction conditions to automatically and intelligently select test bubbles for unknown samples, with the option to choose between intelligent or follow-up. 11. It has an automatic intelligent dual solvent cleaning function, and the cleaning mode can be customized. While cleaning the viscosity meter, the sample cup can be cleaned completely, eliminating the need to clean the sample cup separately. 12. Equipped with a timing calibration port, the instrument can be accurately time calibrated using a standard time calibrator. Technical parameters: According to standards: ASTM D445, D446, ISO3104, GB/T265, GB/T30515 Measurement range: 0.3~10000mm2/s, with a single viscosity tube measuring a span of 100 times. Sample quantity: 16 digits Bath capacity: 3 L Temperature control range: 20-100 ℃ (with built-in Peltier cooling) Temperature control accuracy: 0.005 ℃ Timing resolution: 0.01 seconds Repeatability: ≤ 0.4% Whole machine power: ≤ 1000 W Host size: 400 × 700 × 800 (mm)
