SL-SV4A Four Channel Rapid Automatic Kinematic Viscometer Introduction: The SL-SV4A four channel rapid automatic kinematic viscometer is an automated instrument for quickly measuring the kinematic viscosity and viscosity index of oil products. It is designed and manufactured according to ASTM D7279 and NB/SH/T 0956 standards; This instrument has two independent temperature control units, dual bath four tube, automatic measurement, automatic calculation of viscosity index, and automatic cleaning functions, and its performance is comparable to similar imported instruments. characteristic: 1. Dual bath with four tubes, wide measurement range; Dual bath independent temperature control, capable of testing and cleaning at different temperature points simultaneously without affecting each other. 2. Fast measurement speed. In fast mode, the fastest time to obtain results is 15 seconds, usually within 3 minutes. The entire process of injection, measurement, cleaning, drying, and result calculation generally takes no more than 7 minutes. 3. High degree of automation. Measurement, cleaning, drying, and result calculation are all automatically completed. 4. There are many types of samples for measurement. It can measure transparent and opaque samples, including Newtonian liquids such as gasoline, diesel, kerosene, cutting fluid, heat transfer oil, additives, lubricating oil, and in use oil. 5. Clean quickly and have low cleaning costs. A cleaning process generally consumes no more than 10 milliliters of cleaning solution. 6. Multiple auxiliary functions. Includes: constant calibration, temperature calibration, internal clock timing verification, and automatic conversion of kinematic viscosity to Engler viscosity. 7. Dual over temperature protection, over temperature alarm, and anti dry burn protection functions for both software and hardware. 8. Fast temperature rise and fall speed. The fastest temperature rise and fall rate is 5 ℃/minute. 9. Adopting PT1000 high-precision temperature sensor, the temperature of the constant temperature bath is stable and accurate, with a temperature control accuracy of 0.01 ℃. 10. Disposable filters can be equipped, greatly reducing the workload of experimental personnel in sample pretreatment. 11. Equipped with upper computer software management function, it automatically recognizes samples that meet the viscosity index calculation conditions and calculates the viscosity index automatically. 12. Windows operating system, fully Chinese interface, easy to operate, user-friendly human-machine interface, can be connected to LIMS system. 13. The viscometer can be quickly replaced without emptying the constant temperature bath. Technical parameters: According to the standards: ASTM D7279, D445, D446, NB/SH/T 0956-2017, T/CEC 127-2016, the measurement results meet and exceed the requirements of GB/T265 standard. Measurement range: 0.3-6000mm2/s, with a maximum measurement span of 10000 times for four viscosity tubes Sample dosage: 0.3-1 mL Bath capacity: 3.5 L × 2 Temperature control range: 20-100 ℃ (if the target temperature is below 40 ℃, an additional cooler needs to be prepared) Temperature control accuracy: 0.01 ℃ Timing resolution: 0.01 seconds Repeatability: ≤ 0.5% Whole machine power: ≤ 800W Host size: 405 × 650 × 650 (mm) Working power supply: AC220V ± 10% 50Hz ± 10% Environmental temperature: 10-28 ℃ Relative humidity:<80% RH Other: There is no strong vibration, airflow, strong electromagnetic interference, or corrosive gas around the laboratory.
